Team Fortress 2. I want to have fun in it, but it's too fast paced and annoying.
Counter Strike.
Mass Effect 2. I absolutley loved the first one, but the second is pretty crap.
Left 4 Dead 2. Again, loved the first one, but the second one is crap.
Any Halo games
The Gears of War games. They're not that bad, but they're definetly not as good as they seem to be made out.
Batman: Arkham Asylum. Though i haven't played it, i did watch a playthrough of it to see what the fuss was about, and i didn't find it particularly interesting.
They're the only ones i can think of off the top of my head.
