A whole bunch of dance movies have been made on pretty much the same formula. Just look at the Step Up series and you've already got a handful.
So if you want to be surprised or blown away, look somewhere else. This is just a dance movie. No more, no less.
In some ways this movie is lacking compared to other movies of the genre - for instance while the dancing in it is not terrible it's not as impressive as most other dance movies I've seen. But I'm no dancer so I can overlook that.
It is however not the best in terms of acting. There are some who make it worth it (see next section for details), and some where I was unconvinced to say the least. Unfortunately one of those was the main character, which is unfortunate.
On the plus side, it doesn't take itself as seriously as some dance movies, and in spots it's very funny.
Which leads me to the two biggest plusses; Jordan Fisher and Liza Koshy. Liza Koshy brings the biggest laughs, and Jordan Fisher is the heart of the movie. A lot of the acting in the movie is a little stiff and/or superficial, but Jordan Fisher brings it 100%.
Without these two this movie might only have gotten 4 or 5 stars from me, but they add a little something so it sneaks up to 6 stars.
