Kind of good for me. As a stand-alone action movie, it was decent. However, when compared to the game, imho, it sucked big time. First, they never went to hell, and that was the one part in the entire movie that I was most looking forward to. Finally, they did the whole military squad thing which was a definite let-down to me. Imo it would of been cool to just see the one marine fight his way through instead of with a couple of guys. Plus, they played the whole demons from hell thing as a "virus". WTF?!?!
