This was an interesting and new movie. New you ask? Yes new, as in a new concept, an original movie. It is dense with ideas. No one is truly all good nor all evil. (With 2 exceptions)
If you like thoughtful movies that defy simple viewing than this one is for you. If you would rather enjoy a simple movie than perhaps you should skip this one.
If you don't like the idea of someone truly getting a fitting revenge you may want to skip this as well.
