Indeed, if it's simple, it works. But the irony herein lies when you realize that simplicity and deep thought combinations, make extraordinary things. And this film, in my opinion, is simply delightful. Simple purpose, yet very thought-provoking in itself. I'd recommend it in a heartbeat. Being one of the few who find that the critics aren't always "up to par" so to speak, I think this flick was definately worth it's weight in gold. Go have some fun. Watch this. And when you're through, though you may be left saying "Uh... but..." see if you don't feel the same.
