Quite the surreal trip. This is a very delicate premise because it could very quickly became contrived, convoluted, or pretentious, or all three. But, thanks to the strongly fitting tone, mesmerizing direction, gloomy color palette, and nicely understated performance, this is gripping. Its concept could seem very messy on paper but on screen it comes off as smooth and Hitchcockian, and the score helps more (it kind of reminded me of The Shining). Not a ton happens until the third act, and trust me, after the end, you'll want to look up interpretation and analysis it yourself. Earlier in the film I felt as if it didn't have a ton of depth and that it was a pretty simple story with not a ton else going on. I don't have anything against that but I thought that this could have more to it. However, the last fifteen minutes totally took me by surprised and it makes you rethink the film as a whole, and I'm probably going to see this again to watch it from a different perspective. There's a small timespan of about five minutes where I was bored, but this is one of the best films of 2014. 9.2/10, amazing, far above average, two thumbs up, etc.
