This movie is so bad in so many ways I can't even list them all. Forcing a pretty girl actor to play the role of a demon fighting hero was simply a bad choice right out of the gate. Her character acting and body frame were not at all believable throughout the entire film. She's going to combat a super human strength demon with those twig arms and pretty face? I think not. Any realistic and believable marine would have facial scars from battle, bigger muscles and a lesser cutesy appearance, dolled up to look like a model in uniform.
The acting was bad, the script was bad, the effects looked pretty cheap and the lore was so lacking it was pretty much an insult to the fans who paid to go watch it at the box office. I'm so glad I skipped going to watch it at the theatre. My gut feeling about this movie wasn't wrong.
I do not recommend this movie to anyone, especially if you're a DOOM fan. After watching this movie, I think it's safe to say the DOOM movie franchise (like the Terminator movie franchise) is doomed forever because of being bastardized with forced agendas.
