Enjoyed this. I mean it's deep as a puddle, and the premise is almost incomprehensible, but it was fun and had some pretty decent bits of choreography.

My main criticism is Jared Leto's Joker. I feel like he is capable of making this character his own, but this Marilyn-Manson-impersonating-Heath-Ledger angle was not good at all.

Other than that, I'd watch a sequel. Which is fortunate as I think they made one.
