The plot is quite simple but powerful. It is intelligent from the beginning trying to show you very little as the movie goes along. I was very surprised with acting in general, cinematography, art, editing and music. But perhaps the thing I liked the most is all references to Area 51, and conspiracy theories. From EVE to Genesis project, and quoting the Soviet Union paranormal experiments during the cold war which, now we know, were actually real, at least in their intent. I also enjoyed the several classic science fiction movies homages like James Cameron's "Aliens", Roger Donaldson's "Species", the Resident Evil games and even Steve Barker's "Outpost" if you want, and some others. Perhaps the main issue that generates dislike is the lack of dynamic and rhythmic editing during the 2nd part of the film. The climax to be precise. Nevertheless I think it is a good film for those hardcore science fiction fans that are always searching for new productions.
