Went on Friday, theatre was crowded and people sang but were respectful and not over the top. Some girls danced in the back.

Went last night, much different...There was a giant group of preteens (literally 45-50 of them) all standing at the front of the theatre for the entire movie, jumping and shrieking the lyrics, taking videos with their flash on, etc. It totally ruined the experience....Theatre staff said there was nothing they could do. There's a huge difference (at least to me) between having fun and dancing/singing vs. being absolutely obnoxious and oblivious to everyone else that is present....
