I saw some people comparing this to David Lynch's work. Lynch's movies that are supposed to be ultra-mystery thrillers would actually make an excellent cure for insomnia (to quote Ewan McGregor's character in another movie I'd just watched before this one, "The Ghost Writer"). This movie is one of those you'd need to watch twice (or watch an explanation video on YouTube of it) to wrap your head around it, but at least it never let up, never bored me to death even as I had no clue what on earth was going on to the very end.
