This film has got alot of really bad reviews but i honestly don't know why. It's certaintly better than the 2005 Doom film. Sure it's low budget, but the storyline is decent and theres several Doom references from the games such as teleporters, keycards, demons, chainsaw, bfg9000, UAC.
Seriously ignore the bad reviews and give it a watch. If your a fan of the Doom series, you'll like it.
