If you like this person's taste, follow him!
See it if you are easily impressed. The a capella aspect of it is the only unifying factor in this disjointed story. Other than that it falls flat.
Don't see it if you are looking for a complicated or engrossing story. While amusing at points, none of the narratives ever get off the ground. It was "Ok."
See it if you want something a little different that everyone will enjoy.
Don't see it if you have tiny kids. They won't follow the way it is constructed.
See it if you're a human with a pulse...seriously worth all of the hype. Every aspect is highly refined. The show has something for every viewer.
Don't see it if you have trouble opening your mind to new and challenging experiences. This isn't "fluff".
