I just finished watching this with my brother, and to my suprise, I actually liked it a lot. I really don't understand why some people complain about the acting! I couldn't find one problem with the acting, nor with how the story was.
And I was really glad they didn't make it with it being demons from hell, as Doom 3 was, you know?
I just got to say, that as someone who has never been a huge fan of the Doom series, I really enjoyed it.
Anyone else enjoy it also?
