Coherence is a movie that absolutely impressed me. It's not perfect, but it's genuinely great despite it's few flaws. It's a science fiction thriller that is intriguing in concept, and haunting in execution. It explores themes of self-identity, uniqueness, and the value we place on both. I kinda wish I could leave my review at that. It was word of mouth alone that got me to see Coherence, and the word was simply "great". My friend insisted that this was a damn good movie, and he was absolutely right.
