Well, it's not surprising. You can't exactly name a lot of good game movies. A lot of them just fail for some reason...like Doom unfortunately, that movie had some nice visual effects and what not but no real point other than to just kill stuff, and that doesn't work in movies (at least when the movie doesn't have a plot...or much of one). The only real game movie I can think of that I like is the old Sonic The Hedgehog movie. Sonic vs Metal Sonic = Fun Fun. Hopefully if people continue to go after game movies though, they'll attempt to make it more interesting for people in general, and not just the gamers interested in the game.

Its because they dont even have anything to do with the game story line. Its just losely based on the game and ends up geting screwed.
