This is a beautifully shot and directed film, and the casting is superb. Jared Leto has outdone himself this time, his acting was so incredibly moving. I can't wait to watch it again and again, as I think it is a film in which there are so many brilliant moments and touches to take in, I may have missed some of them.
The idea that one drop of water can change the course your life can take, and where that drop came from, is beautifully done. I enjoyed this film immensely and I will do so again. The score is also wonderful, very simplistic and yet incredibly effective.
In short, I really love this movie, and I would recommend it to those who enjoyed The Fountain, I Heart Huckabees, or basically anyone who is a bit of an existential, "what's it all about" movie fan!
