Confusing and completely foolish....one of the worst movies I have ever seen!!!!

The first 15 minutes are interesting, could have been better explored.....when it turns into a "science fiction " movie it derails.... The story falls apart....it becomes a sequence of nonsense and lack of continuity.....cannot understand how this B movie became so praised by critics.... Having been awarded the Oscar for Best Movie is hard to understand....in a year that had several really good movies competing ..... Acting as well seems unnatural, forced, grotesque.... This year's Academy winners indicate that Hollywood standards are changing.....for the worse.....
