I honestly loved this movie. I found it so interesting and psychological the whole way through with time loops, endless questions and just such creative visual choices. Yes there were some plot holes and a whole lot of questions left unanswered however, I feel that the fact these questions are left unanswered adds to the movie. I have seen a lot of reviews saying that they didn't understand what was causing the strangeness of the field and what the rock was doing and thus marking down the movie for it, but I don't want an answer. It is one of those movies for me that is more impressive and unique the less you know about it. And I say that in a good way. The fact that I have no idea how that field worked and why it is like how it is makes me appreciate the movies originality so much more. It actually angers me that top reviewers have not given it the credit it deserves. The story, acting and execution in this movie was incredible and I highly recommend to give it a watch. I do admit if you are going in to get scared, this movie may not be for you, however if you want to piece things together and just admire its peculiarity, definitely give it a watch. (p.s. Don't read a rotten tomatoes revue and decide if it's good based on that, because this movies deserves so much more)
