Surprisingly not bad. Strangely I found out about this movie because "pornstache" from Orange Is The New Black is in it, although very briefly. Although of course once I saw it was a ScarJo movie I was definitely in. A bit too much narration in the beginning; it does taper down but it's still present here and there all the way through.
Ok so it's a movie about dancing, but I didn't expect *that* much dancing. Also didn't expect that much craziness either! And there certainly were a number of gross-out moments as well, and a couple of gratuitous make-you-jump orchestra hits.
I'm not surprised to see the ratings the way they are, I do tend to like the ones where critics are much lower than the users. Although I'd've expected the users to be a bit higher as I thought it was a decent / pretty good movie. Twas a bit short, and ever so slightly corny, but had a lot of good actors in it, and I didn't have a problem with them taking many liberties with the story.
