I just finished
TMNT the 360 game. So crappy. How crappy? The whole game can be more or less slept through, including a couple mindless boss encounters. But the end of the game requires some insane, timed platforming, and then culminates in a multi-stage, start from the beginning if you die multi-boss battle with single-hit knockback/fall to death gameplay AND a mechanic that they only mentioned once, halfway through the game.

Oh,
Guitar Hero III. Not a bad game, but the worst, most stingy Achievements of any game I own. I've played the hell out of it, and still only have less than 300 in it.
Crazy Taxi Double Punch (PSP). This would probably be a good game if the controls could be remapped. I can never get used to controlling something which has different controls than every other driving game on the PSP.
I've got a feeling
Warhammer Battle March is going to end up on this list if I ever open it
