Wrong, wrong, wrong. The real reason why video game movies usually suck is the same reason why movie video games usually suck. The creators/developers/whatever see a license and yell "Squee! Instant popularity!" and then stop actually trying to make something good. It doesn't have anything to do with the formats - it has to do with laziness in translating between them, not to mention a certain director's habit of picking games that would make terrible movies. I mean, come on. Dungeon Siege?
