A masterpiece! One of the most thought provoking, spiritual and hauntingly didactic movies I've ever watched. It touches you at a very deep level if you let it. The movie can be interpreted in a lot of ways but however you look at it, there are many parables that can be drawn. The movie is about consequences, free-will, the ephemeral nature of true love and the problem with wanting too much of a good thing, a dream-like world if you will. When we only dream and not live in the real world which is filled with both pleasure and pain, our make-belief world eventually rears its ugly head and gives us a reality check, which is exactly what David goes through in his warped lucid dream.
Every action, however small, has consequences - if we take a step back and review our own life's timeline, we will probably realize that all the significant events started from something very little ("The Little Things. There Is Nothing Bigger, Isn't It?"). My favorite quote from the movie is "The Sweet Is Never As Sweet Without The Sour". I interpret this to mean that we can only have a true sense of life if there are ups and downs. We only learn to do better after making mistakes and experiencing some pain. The last lesson I got from the movie is that perfection does not exist and is a seductive illusory entity that sucks us in and depresses us. We should learn to unveil the masks we hide behind everyday and accept ourselves and our reality for there is beauty and hope even in our so-called ugly, problem laden lives.
A must-watch!
