This movie was based off of Doom 3. When you watch it, you'll notice some similarities. I've played the game and it's great, but the movie unfortunatly doesn't live up to the game. It reminded me a lot of the resident evil movie.
Pros. about the movie: great special effects, gore, first person camera angels, cool monsters, guns and explosions, oh yeah.
Cons.: not much of a story, plot is pretty basic, starts off too quick, didn't have the same feeling when playing the game and the acting is moderate. The one thing that they changed from the story in the game is that the scientists don't open the gate to hell, they make it a genetic mutation that makes everyone turn into zombies. So sad.
So far, this is the best game movie out there, but still doesn't match up to the game. It should of been more scary, gory, a better story and had them open a gate to hell. If your making a movie from a game, make it like the game. Same looking characters, enviroments, atmosphere, don't ad in heavy metal music just to make the movie better (e.i.doom, resident evil) and don't change the story, (unless it's extremely cheesy).
P.S. You don't have to have well known actors and actresses to make a movie good. Come on. (e.i. dare devil, electra, cat women, x-men, resident evil.)
