i've seen some good gaming films, but then again, i'm not much of a film critic.
Resident evil: fun
Resident evil 2: better
hitman: sweet!
although i'm really happy that i've never seen any film by Uwe Boll (whoever/whatever gave him the idea to make gaming movies should be hung, drawn and quartered), although i have a feeling it'll change in the future, seeing as he's making Far Cry, and from what i've seen, the storyline is nothing like the game. nevertheless, i'm still interested and i'm going to watch it.
though i've got a feeling people won't agree with me, i'm not very keen on the GoW film idea, simply because:
1. its storyline wasn't really top-notch
2. you can't really expect a movie about it to be a lot better.
