Good concept, poorly executed.

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
