I saw it today. The hairs on the back of my neck stood up on some the tracks. I loved it and it's not my normal type of film. I've been dancing around to the soundtrack since and man oh man Zac Efron was hot in that film.
It's really uplifting. Went to see it with my 12 year old and we both loved it (and she is quite the discerning musicals fan - one of her favourites is The Music Man). My only quibble would be that it was quite short. Love the songs though.
