To each their own I guess, I found it to be worse personally (though I have a rather negative bias to most things related to HG/SS in general so that may be a part of it).
That is a good point, and I don't disagree with you completely either. I would probably have preferred to have the Frontier over the Maison but the Maison is good enough for me and I have already played through the majority of the Frontier in Emerald so I don't mind it that much.
Some quick thoughts on all of this. I didn't watch the whole video but checked out all of his opinions.
(numbers in reverse order)
10. Squirtle and Charmander seem to be the more well-liked Kanto starters so I think this is a bit unpopular. Bulbasaur is my personal favorite nowadays even if it wasn't the one I picked the most when I played the Kanto games as Squirtle used to be my favorite back in the day.
9. Hoenn seems to be rather well-liked around the community still, so I don't think this is that unpopular. Or at least, it was before OR/AS. I think it's pretty good too even if it isn't my top favorite as that honor goes to Unova.
8. Several Unova Pokemon still get far too much hate in my eyes, so this is definitely unpopular. I have seen so much hate for them both in this thread and at other places and it makes me sad every time. Especially when people hate all of Gen 5 for one or two Pokemon designs, those kind of people should quit being Pokemon fans. I agree here as I think all Unova Pokemon are awesome. Though that goes for all other regions too, but I'm a tad biased and more defensive when it comes to the Unova Pokemon since they were the ones introduced in my favorite generation.
7. Unsure if this is unpopular, Kanto seems to be either loved or hated by everyone, few people put it in the middle, it seems. I personally agree with him as Kanto is my second least favorite region next to Johto, it just isn't as interesting as Unova, Kalos, Sinnoh or Hoenn to me. That's not to say that I dislike Kanto (as I surely don't) but it is far from my favorite.
6. Unsure about this too. Both B/W and B2/W2 have been hated in the past but nowadays, it seems like they are a bit more liked among the fandom in general compared to what they were in the past. But since neither seems to be the very top favorite in the fandom, I think this is somewhat unpopular at least. My opinion? I can't agree more as B2/W2 (and B/W) are my favorites and I had so much fun playing them.
5. I don't think this is that unpopular, R/B/Y don't get a lot of love these days outside of nostalgia-blind Kanto fans who don't really go to Pokemon forums that much. Personally, I agree, I don't think R/B/Y are the best either. Though I had a lot of fun with them when they were new, but to me, they just can't compare to the newer games. I agree with him on FR/LG too, and I think liking them is definitely unpopular.
4. Not sure since I don't watch the anime, and no opinion of my own since I haven't watched all the openings.
3. This is probably unpopular. One of the main reasons people praise the Johto games are because of its "massive post-game" (which in my eyes is not a good post-game, but we'll get to that), not so much because of the Johto region itself. Face it, Johto doesn't have a good post-game or even a Pokemon League of its own. As for me, Johto is my least favorite region (though I wouldn't go as far as to say that I dislike it) and I think its post-game of Kanto is vastly overhyped and overrated, not really deserving of any praise.
2. THIS IS UNPOPULAR. I am sometimes concerned for the fandom because of all the hate and dislike we are spouting on a game series and a franchise we are supposed to be fans of. Seriously. Whining and complaining about everything and anything has become kind of the main thing we do here in the fandom. It shouldn't be like that. I think people need to actually appreciate
what we like about Pokemon much more as opposed to just complain about the bad things. Either that, or some people should quit being Pokemon fans. I know I'm guilty of being a negative idiot at times too, you don't need to tell me that. But anyway, I agree with him.
1. Probably unpopular again since most people seem to have one favorite and one least favorite. But deciding which is the objectively "best" is practically impossible (so that's actually not an opinion, but an objective fact). Personally, my favorite is Generation 5, but I can't say it is the objectively "best" because I know others will disagree with me. Likewise, HG/SS are my least favorite games, but I can't say they are objectively the "worst" for the same reason.
Finally, as for HG/SS being his favorite games... From what I have seen around the fandom and various Pokemon forums, HG/SS generally seem to be very well-liked and are usually at the top spots in polls, so I don't think liking them is unpopular at all. Which might be a reason as for why we don't see a lot of praise for them in this thread. Though, this is just from my perspective. Then I do personally not like them which might affect my view on them, but I don't know. If anyone is of a different opinion regarding liking HG/SS being unpopular or not, feel free to say it.
