May as well explain why I hate each of these games:
1. The Legend of Zelda: Majora's Mask
The only thing there really is to hate or love about it: the time system. Completely ruined the exploration for me. Yes, I know there are ways to set back the clock, but having time limits in a Zelda game has the same bitter ring to me as if animated Disney movies started to swear and use blatant product placement.
2. Sonic and the Black Knight
I actually did enjoy a number of despised Sonic games, like Shadow the Hedgehog, Sonic and the Secret Rings, Sonic 4, and Sonic Unleashed (including the Werehog stages). Even Sonic '06, as awkward as this is to say, was better than Black Knight. Black Knight just felt dumb, uninspired, and rushed. I felt embarrassed just playing it in a room by myself.
3. New Super Mario Bros. 2
The coin powerup was dumb and kept killing me because I kept forgetting it doesn't make you invincible. The level design was boring and uninspired and the music was annoying and repetitive.
4. Final Fantasy VIII
The frickin' GF system or whatever it's called. Annoying to set up, made attacks take way too long, and dampened creativity. The game was also a little slow-paced for me and I didn't care about any of the characters or the plot.
5. Pokemon Black 2 and White 2
Boring and redundant (at least considering that I expected actual sequels rather than Crystal-style remakes). I haven't even beaten the 7th Gym yet.
I will never, ever, ever get the praise for these games. Borderline unplayable.
The platforming can be awkward if you don't take time to get used to it, especially if you invested a lot of time into the Genesis ones first and thus weren't accustomed to having (and needing) the homing attack. I don't think they are that praised, though. I mean, maybe SA1 and SA2 are, but it seems like Sonic 1, 2, 3, and Knuckles for the Genesis are still held up as the best in the franchise by far.
