Oh yeah, I've got a few!
Smash Bros. Brawl- The weakest of the Smash Bros. series to me. Far too slow paced, Subspace Emissary was a pain, Break The Targets was boring, and the Classic and All Star modes felt so gimped. It's a decent game still, but pathetic compared to all the other Smash games IMO.
Ocarina of Time- Oh yeah, I went there! It's a good game and all, but the best game of all time? Come on, that's a bit of an overexaggeration! Even in terms of the Zelda franchise itself, there are better Zelda games to me, such as Majora's Mask and Breath of the Wild! Maybe I'm a bit biased towards this one since I've never really been a Zelda person, but I honestly don't think I'll ever see this game as one of the greatest of all time. It's just a well done and fun Zelda game.
GTA San Andreas-An awesome game, but I fail to see how its the best GTA. 5 and 4 (especially 5) had more engaging characters and compelling worlds IMO. It's an awesome game but calling it the best GTA seems too heavily rooted in nostalgia to me.
Sonic and Sega All Stars Racing (Both the original and Transformed)- the only game (or games) on this list that I actually dislike. They're not terrible by any means, but TBH they're little more than shameless Mario Kart knockoffs. They're certainly better than the riders games and Sonic R, but they're still not what I'd call good.
That's all I can think of for now.
