on the topic of semi-unpopular(it's pretty mixed) takes, gen 8 is good and here's why I'm right and why you're wrong
Ok now that we have the clickbait title, I actually do think that gen 8 is on the better half of the series, if not on the top half in spite of its flaws(at least shield, I have a bit more gripes with sword but they're mostly the same game). No multiplayer commentary though sry, I really don't give a shit about in-game multiplayer outside of trading for the shiny charm which works easily enough, codes are a very easy way to connect to specific people vs how clunky SM's friend list was(and how names just refused to show up sometimes cause fuck you lol). This is more of an opinion piece about why I enjoyed Shield in spite of downsides, certainly not a defense of it because it has notable flaws that I don't put it past people disliking.
The Good
* Since I played Shield completely blind, I had no idea what the dex was going to be and my biggest fear getting the games would be that I ended up finding most mons mediocre like I did in gen 7(that I knew the entire dex before even buying Sun) but thankfully I found probably the second best dex in the entire series. Finding every new mon was one of the most enjoyable parts of the first playthrough I did, between the regional forms completely blowing alolan forms out of the water, and the creative and fun new mons, it was just a great experience. The "oh my god I need that" moment when I saw Nessa send out an Arrokuda, the cutest derpiest fish I've ever seen, is one of those moments that defines the dex for me and is largely the reason why I've since played gen 8 more times than I've played gen 3/4/7. Overall I feel that Galar has one of the best regional dexes in the series and the new mons have so much charm to them that have been generally missing in Kalos and Alola.
* Gamefreak is getting shockingly close at giving us actual characters for once, it's surprising but true. It certainly isn't perfect and most gym leaders suffer from "only appear once" syndrome that prevents them from having much character at all, but on the other hand you have some of the most memorable characters in the series. Hop gets a lot of hate for some reason(never got the Hau comparisons, they're not similar characters) but I think he's a pretty great example of there's room for good character growth that's possible in the rival formula GF uses, I will call him out for being almost too similar to Bianca minus the over protective father. Then you have the gym leaders and wew we got some gym leaders. Opal and Raihan are up there as some of the best gym leaders of all time(Getting to see Opal radiate theatre energy made me fall in love with her character as soon as I saw her). Trainer cards also help a lot giving characters some added depth so we got to know more about the earlier gym leaders with Nessa and Kabu, and while I didn't particularly like Bede I will say he's a well written character who's arc feels satisfying. I think it's obvious without going into detail that I like Leon and Raihan.
* Galar as a region is beautiful(besides 2 main gripes that'll be later). I think Galar has some of the nicest looking cities/towns we've seen. Going into the Slumbering Weald for the first time was such a mysterious almost ominous feeling, it was oddly atmospheric for a Pokemon game lol. Postwick and Wedgehurst are great starting towns that give you the feel for the aesthetic of Galar, the old rustic look of Motostoke, the regal looking Hammerlocke perfectly capturing the rich central area that most regions have, Circhester being gorgeous, and Wyndon being massive but not annoying to get through *cough* Lumiose. You can't talk about Galar's amazing scenery without talking about the Glimwood Tangle and especially Ballonlea are stunning to see, the glowing mushrooms are brought out so much by how dark the forest is, and getting to Ballonlea is like the exact type of place I'd expect a town in a fairy forest to look like, it's enchanting. The dlc islands are also very visually nice to look at.
* The music. Really don't have much to say here, every track hits way harder than it needs to and SnS has my 3rd favorite OST in the series. Though I hate how gen 7 and 8 both recycle old pokemon themes instead of having actual champion themes, I prefer remixes for post-game battles and callbacks, it's just lame to have the big climactic moment just be a theme we've heard a thousand times already. Leon's theme is decent though so I don't miiiiind it, just a gripe. Toby Fox's one is also pretty good so that's smth. Ballonlea's theme is the best town theme in the series.
* SnS is generally more difficult or easier depending on if you use dmax or not, some matches like Nessa, Allister, potentially Opal(depending on your team, I've had sweeps and I had times I got swept lol), and potentially Raihan are all challenging battles. Allister being the main challenge because a SpA buffing Gengar is surprisingly brutal at that stage of the game. Leon as a champion is also probably the hardest champion albeit he doesn't have much competition, he doesn't have mons that let you easily set up against him so he can't be cheesed like Cynthia can be.
* Team Yell isn't the same copy/paste evil team we've had for 7 gens now. Hell Galar doesn't even have an evil team, Macro Cosmos is a functioning company in Galar and only fights you when you literally -break into- Rose's Tower because Leon promised dinner and hasn't shown up. I do like how Oleana is totally batshit insane but otherwise not a villain even though she sooorta takes that role(which again you're literally breaking into a building lol).
* The QoL, this is more apparent in IoA because there's just *so much* QoL additions in that dlc but gen 8 just made everything much more convenient to get which I like a lot. the CT dlc as a whole is a great experience too.
The Bad
* Dmax is the worst mechanic Gamefreak ever added in a Pokemon game to date. Gmax is a cute idea and I actually like a fair bit of the gmax forms but it's overshadowed by just how broken dmax is, and hilariously most gmax mons are unviable because the dmax alternative is just better. Only way I could approve of gmax existing is if they just entirely deleted dmax moves and just let gmax mons have their 1 signature move and the HP buff.
* While I find Galar a really nice to look at region, there are 2 big flaws. The shape of each town/city/route is just a line pretty much, this really ends once you get to the route going to Circhester though, bar Spikemuth which is yk ----- shaped lol, I get the arcade beat'em up reference but man...
It does suck though, Ballonlea is 3 buildings and a gym, Hammerlocke is just ┴ shaped, Stow-on-side is a Y, Motostoke is an uppercase i(gdi fonts that make I look like lower case L). Makes actually exploring Galar pretty much not an option which is probably the biggest gripe I have about the game as a whole. The other big flaw is the base Wild Area, which is a cool idea but I feel like Galar as a whole region suffered because of it. I don't really have anything to add that hasn't already been said a thousand times but I will say the wild area was fully realized in the dlcs at least.
* They removed Me First :( but yea besides that I didn't really notice that they removed moves from the game, the mons missing from the dex is only really relevant if you transfer mons across games so it didn't personally effect me at all and my favorites were all added in IoA. It is the notable downside to SnS though so I have it listed here, it's honestly a bit overblown though imo.
*While the characters are generally good I feel like some miss the mark, Bea is significantly more boring than Allister(doesn't help that Allister is significantly harder cause Gengar) due to her being nearly indistinct from other fighting specialists in the series outside of her design. Gordie and Melony generally received the least screen time of any gym leader but they are both memorable(even though Gordie's team is completely trivial). Marnie is saved by having the best battle theme in the game but as a character, Gamefreak just...dropped her for no reason. She completely disappears for half the game from the first time you battle her, you don't see her again until you get to Opal's gym where you don't even fight her. Then you FINALLY see her a 3rd time before you fight Piers. She definitely needed 2 or 3 more appearances in that large gap where she just disappears, especially since you have a few encounters with Team Yell during that time. It's not an uncommon or surprising complaint to say that Rose's character is handled really badly, they really should've just made Eternatus wake up due to excessive use of dmax during the Champion Cup. Would've had the same outcome without Rose being a last minute "oh fuck we don't have an antagonist we need to pull smth out of our ass."
* The game is easily broken, when I said "SnS is easier depending" that is a bad thing imo. If you have to restrict yourself from using a broken mechanic to sweep the game, it's not a hard game. This is really what pokemon has been struggling with since gen 6(lol free mega lucario and mega lati before the 4th and 6th gym respectively) and it really hasn't gotten better especially with things like EXP candy letting you easily over level as it's easy to get them in bulk once you have a few gym badges even if you just casually do raids during the 3 required visits to the wild area. This is more noticeable in Sword than Shield as Bea and Gordie are trivial compared to Allister and Melony. Not to mention Zamazenta Hop is a joke compared to Zacian Hop. I won't judge the dlc characters much since I've never seen Klara but I do like Avery a fair bit.
* Free move relearners is great and a huge QoL improvement over SM locking it till the E4, but you have an issue when gen 8 also gives you every single evolution stone in the wild area at the start of the game...meaning you can get an Arcanine with flare blitz, Musharna with psychic and moonblast, Vikavolt with bug buzz and tbolt, and Ninetales with nasty plot heatwave before you have 1 gym badge.
* The starters are still bad imo. Cinderace is possibly my 2nd least favorite mon and that's saying something cause I thought I disliked Braixen a lot, at least Braixen evolves into an ok mon though. Rillaboom is okay and I like Inteleon more than a lot of people but it's still just average, the NFEs are god awful though. You got whatever tf Thwackey is, emo frog, and naruto rabbit, skip them.
(jesus christ I didn't intend on this being a whole ass book lmao)
