On top of all this with Gen 2 HGSS hate becoming an increasingly popular stance the older fans who never bought into the hype to begin with (e.g. Volt-Ikazuchi, DrumstickGaming and Suspicious Derivative just looking at this forum) are emboldened to speak out themselves.
		
		
	 
I’m not surprised that you mention me as an example of a player who dislikes HG/SS. At this point, I guess it should be clear to most OI veterans that I am not very fond of those games. However, the reason I am quoting you is because you are actually wrong about one thing. Unbelievable as it may sound, there was actually a time when I bought into the hype for HG/SS! Back in 2009, when they were first announced, I was burnt out on Pokémon. I had basically overplayed D/P and Emerald, while the games that were released before them were not as interesting to me at the time. Platinum, while a great game, did not manage to restore my interest in the series. Though I can appreciate it a lot more in retrospect, and I think it is the best 4th gen game without any doubt.
Either way, regarding the announcement of HG/SS… as an older Pokémon fan, I played G/S/C as a kid and had tons of fun with them. Silver was also my second Pokémon game. Since the hype for Johto remakes was extremely high in the fandom during Gen 4, I sort of just got into it as well. I was not super aware of the flaws of G/S/C at the time, so I got blinded by nostalgia and was looking forward to HG/SS just like everyone else. I thought, hoped and expected that these remakes would restore my interest in the series. I got SS on the release date, and then I ended up getting HG much later (but for a while, I was actually considering not getting it). However, when I got around to playing them, they weren’t as great as I had expected. The more I played them, the less I liked them. In the early parts of the game, I remember that I got very annoyed by the fact that the following Pokémon couldn’t be turned off, how you couldn’t properly choose which Pokémon should be following you, and how badly executed the feature was in general. Regarding the available Pokémon during the main game, there are definitely some useful Pokémon. But I felt that there were way too few Pokémon that I found 
fun to use. Despite those and all other issues, I beat the main game of both games without too many issues.
The real issues started in the post-game. HG/SS often get praised for having a good post-game or even the best post-game in the series. But I disagree. I tried to enjoy the post-game of HG/SS, and I really wanted to… but I couldn’t. There were just too many issues to make it enjoyable. In SS, I remember that I tried to complete the Pokédex and that I managed to complete at least 3/5 of it, but I just gave up after a while. It wasn’t fun at all. I didn’t get around to completing it until 2015 (in both games). Regarding HG, I remember that I played through the main game and then beat all the gyms in Kanto, then I just quit playing. Continuing with the game afterwards did not feel motivating at all. In the end, I find the post-game of HG/SS to be really bad. There isn’t a lot to do, and the few things they have to offer are very poorly executed for the most part. I don't think they have the worst post-game in the series, but it is very bad, that's for sure. I also need to mention that nowadays, HG/SS are my least favorite games in the series and I even liked G/S/C better than them.
The flaws of HG/SS became even more apparent after I played B/W, which ended my burnout and got me back into Pokémon. Going from HG/SS to B/W was like going from garbage to pure gold. B/W were practically the opposite of HG/SS in almost every way, they were fun and enjoyable where HG/SS weren't. I love B/W for that and pretty much everything else they did.
One other thing that was mentioned here which I think is very interesting is the fact that HG/SS doesn’t seem to be all that loved anymore. If anything, I see a lot of criticism towards them these days. Especially here on Smogon, but I have seen it on other sites too. It is strange, because in the not-too-distant past, they were generally considered the best games, flawless masterpieces that were immune to all kinds of criticism. But that seems to have changed. These days, other games seem to be more popular, notably Platinum and Gen 5 (which I personally approve of as I think those are much better than HG/SS). Even the 3D games seem to be rising in popularity lately, which is interesting. Things are changing on the whole, and I guess it shouldn’t be too surprising, yet I still find it unexpected.
That’s all I’m going to say about HG/SS this time. If I were to continue with saying more things, it would just be repeating what I have said in the past. If anyone wants to read more about my unpopular opinions regarding HG/SS, see 
here and 
here.
Now, to something different. Since the subject changed from HG/SS to Gen 5, I want to share two unpopular opinions about Gen 5 as well. I am pretty sure I have posted both of them in this thread before, but I want to post them again.
First of all, I think B/W has a great post-game. From the first pairs, I think they are tied with D/P as the best in the series. When it comes to post-game, I find these two pairs to be much better than R/B, G/S, R/S, X/Y, S/M and S/S (without DLC). I loved the post-game of B/W. You have large new areas to explore which feature strong trainers, strong wild Pokémon, and new wild Pokémon that couldn’t be found during the main game. There are also the Nimbasa Stadiums which are a great training spot. HG/SS has a lot to learn here. B/W has a fun and challenging Battle Facility in the Subway, there were also Dream World and online features before they got closed down. I liked the Entralink Missions too, and another unpopular opinion I have is that I liked the Musicals as well. Overall, I think the post-game of B/W was great. Not the best in the series, but tied with D/P as the best from the first pairs, and I think it is considerably better than the awful post-game of HG/SS.
Second, I liked the story in B2/W2. Not as good as the one in B/W, but still enjoyable. I liked seeing how things had changed over 2 years, the return of old characters and the introduction of new ones. It was interesting to see Team Plasma getting split in two different fractions as well. I want to give a special mention to Colress as he is one of my favorite characters in the series. This is because I can relate to his desire to make Pokémon stronger by natural means as that is something I am personally interested in as well. Basically this:
		
		
	
	
Overall, I think the story in B2/W2 is the fifth best in the series, beaten only by B/W, S/M, OR/AS and Platinum. In comparison, I think HG/SS has the worst story in the whole series.
	
		
	
	
		
		
			Okay if you want my real opinion, I actually get some enjoyment out of every single mainline Pokémon game*. Even for the most flawed games (IMO OG DP, XY, and SwSh), I can derive enough enjoyment from that I still think they’re at least OK. Call me easy to please, but for me it really just speaks to the strength of the core gameplay.
		
		
	 
I mostly agree with this. Like you, I haven’t played LGP/E, but apart from that, I have found almost all other Pokémon games to be fun and enjoyable to play. If not nowadays, then they were at least good for their time. Some of them have serious flaws which can get in the way at times, but even so, they were fun. To me, there is only one exception, which of course is HG/SS.
Since genning Pokémon was brought up, I want to say something about it as well. I have personally never genned a Pokémon and I will never do it. I used to be strongly against genning in the past, but nowadays, I am okay with others who do it in some situations. If you are genning Pokémon for personal in-game use and nothing else, that’s fine with me. If you are genning Pokémon and using them for online battles or unofficial tournaments or something similar, that’s also fine by me as long as everything is legal
/legit (not sure which word is correct) and if you say that your Pokémon are genned when battling another person you are in contact with (and as long as the person in question is okay with it, of course). What I’m not okay with is using genned Pokémon for official tournaments or VGC. Neither am I okay with someone trying to get on the leaderboards for Battle Facilities with genned Pokémon. Though I am okay with people who use genned Pokémon in Battle Facilities if they are just playing for fun and not planning to get on the leaderboards. Apart from that, I am not really okay with trading genned Pokémon. However, similar to battling, I suppose trading genned Pokémon can be okay if you say the Pokémon is genned and the person you are trading with is fine with that. But otherwise, I am not okay with it. So that’s my view on genning.
I should also mention that while I don’t do genning, I do RNG abuse on Gen 4 & 5, which I know some players consider to be cheating. And I think they are entitled to their opinion, I just disagree with them (see the Colress image I posted above).
Edit: Legal was the word I was looking for, thanks Siggu.
