This is one of a kind for sure. A concept which is not new, but still feels fresh.
Reminds me of a mix of Momento, Black swan and Gone Girl! One of these movies where you would benefit from a second screening, as everything is shut out of sequence. As I have seen this movie on a festival and it was my 7th for the day, you might have an easier time watching it, when your brain is actually still on 100%. The story will soak you in and confuse you at the same time. I actually cant wait to watch it a second time.
I've always been a big supporter of Eric Balfour and he is actually pretty perfect for this role. I am not totally satisfied how the story of his character is concluded though, but I'm happy to see him in a good movie again after such a long time.
If you are in for a different kind of cinema experience, give this movie a chance, be focused on what is happening and have fun dealing with all those puzzles pieces later.
