I'll tell you why so serious

Clever, believable, and super fun to watch. It totally has replay value.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.
