As a sort of Alien prequel it certainly ticked all the boxes. Not as scary though; more sci-fi than horror. I won't give any spoilers here but suffice to say I have a feeling there might be a sequel to the prequel in the pipeline.
Michael Fassbender was excellent although Guy Pearce looked a bit weird.
The film did give me nightmares that night so it obvious affected me more than I'd first thought.
I have a feeling we might be seeing it again rather soon...
