OK, let's get this fact out of the way: I'm not a big fan of Alien. So, why did I buy the bluray of the "prequel"? I didn't see it in the theater, but the trailer looked fantastic and interesting. Sometimes that is enough to fork over my hard earned money.
What did I think? The plot seemed try to cover too much back story. But the cinematography was fantastic - wished I bought the 3D bluray for that reason. There were strong characters with Dr. Shaw (Noomi Rapace) and the android David (Michael Fassbender) as standouts. I want to say that the first half was better than the second half of the movie. About the last 20 minutes were put on mute and I enjoyed even more.
Look like they will try for a sequel since we see Shaw and David ride off to find answers. I would personally like more on the "Engineers". The deleted and alternate scenes were IMHO actually better esp the beginning with the Engineers. Overall 2.5/5
