I saw it a couple of months ago and yeah, the gore was glorious indeed but aside from that it was tough to get through. The acting was atrocious and so was most of the dialogue. Oh, and I loved the fake-out ending. Haha.
I read somewhere that 20th Century Fox tried to sue the makers of this film for using the "Alien" name but supposedly the producers managed to convince a court that their film wasn't meant to be a sequel to Ridley Scott's "Alien" but to a science fiction novel from the 1930s that was also called "Alien." Wow. They must've had a one helluva slick lawyer, or a gullible jury.
