I am not sure whether this article will get flagged or not, but I agree completely with you on this. I watched it last friday and wasn't even sure what this movie was about. For the first half an hour I was cursing myself that why did I came, however, everything changed.
This is one of the best sci-fi movies I have ever seen, and I have seen almost all. I am very sure that most of the HN community will love it.
