It's not exactly uncool on the Escapist, but elsewhere on the 'net admitting you like the new DmC will get you set on fire. It's a fun hack 'n' slash, just not groundbreaking. I can understand why DMC fans are disappointed but, for me, it was a wonderful game.
I really liked Crysis 2, even if I agree that Crysis 1 was better.
Chuck Rock was considered to be yet another generic 2D platformer at release, but I still had fun. The level design was quite open and the aesthetics were very charming.
Toejam And Earl: Panic on Funkotron was considered a sellout because it went from the original's bizzare top-down treasure hunt gameplay into a 2D platformer. It was anything but generic, though, with it's extremely open levels filled with secrets and downright weird enemies. One of my favourite games from the 16-bit era. I prefer it to the original.
As for games that are usually considered genuinely bad...
I really enjoyed Shadow The Hedgehog. It did so many things wrong, but I just love running around, holding the fire button and watching things explode.
Last Battle on the Megadrive was normally considered boring and repetitive but I found challenging and enjoyable.
There's something weirdly engaging about Drakengard. The gameplay is inexcusably boring, both the graphics and the aesthetics are ugly as shit and the story is so bleak and everyone is such an aresehole that you just don't give a shit. I couldn't tell you why I like it, it's a terrible game. Maybe it's because I played it when I was an angsty teenager who loved grimdark, I dunno. It's sequel was marginally better, but Nier was a massive improvement and a game I think deserved a far better reception than it got.
