I gave it a C. As a big fan of the last movie I wanted to like it, but with this movie basically being a rehash of TWOK it just seems like they're repeating history. Wasn't the whole point of the alternate universe to move away from what happened before? The 'cute' throwbacks to TWOK meant for fans at the end basically took me right out of the movie, ironically a non-fan probably would have enjoyed that more! On the other hand, the music, acting and special effects were all top notch at least.
I'll still buy the DVD, because I'm a completist, and hopefully it grows on me as time goes by!
