I wasn't even thinking about the post-Genesis/Mega Drive games.

Unpopular opinion about the Sonic Adventure gamesI have a very unpopular opinion of the Sonic Adventure games, I feel. I don't think, as a whole, they are very good. The Sonic areas (and Shadow in 2) are very masterfully designed and fun to play. Other than that, though, I just can't stand playing as the other characters. I find their sections badly designed in some cases, or just boring to play in general. Adventure 2 was a bit better in this regard, but I still feel largely the same about it. I will also concede that Adventure 2 had some interesting things in its story by the end of the game.

I'll add insult to injury here and say that I prefer Sonic '06 to the Adventure games. Yes, Sonic '06 was unfinished when it was released and is glitchy to all hell, but I found the gameplay with the non Sonic/Shadow characters to be a lot more fun. Blaze is probably my favorite of the bunch. The Sonic/Shadow levels in the Adventure games are a lot better than any of the levels in Sonic '06, but I like the overall package of '06 better.

Generations is my favorite of the more modern games, though. I also really like the Sonic Unleashed mod for Generations. Sonic 4 episodes 1 and 2 are garbage I think. Lost World actually looks to be a lot of fun despite the reviews it has gotten. I'm wanting to try to work my way through all of the series, though. I own Heroes which will probably be the next one I try to play eventually.
