This movie is a typical 80's macho action...filmed in 2005.
What gun is that supposed to be?
When are the demons from Hell showing up?
What game is this an adaptation of?
Why didn't id Software sue for copyright infringement?
On the bright side, adrift in a sea of tedium: the fist fight is cool, the tongue things are nasty and there's some impressive gore. But I only remember one of those things from the games.
Contrary to Rotten Tomatoes insulting consensus, fans of the games are going to be the most disappointed of all.
