I suppose we all know that movies based on video games really aren't that good. Most of them suck, while others manage to be decent, and with movies based on games like Tekken, Metal Gear Solid and American McGee's Alice coming up, Hollywood seem to really, against all odds, have accepted video games as a way to tell a story (= make some money).
But anyway, what's your favourite movie based on a video game? (Animated movies are not excluded)
