Big stars + Bad movie = Big Yikes
First off: The visuals are so bad they make me almost want to barf
Second: Adding big stars (especially Taylor Swift) would make it an intolerable attention grabber.
Third: There is a severe lack of a plot
Final: Some of the dance moves are very inadequate for a PG rating.
If someone actually listens to me, cancel this, fully animate it, make it look cartoony, and add a plot. This movie has a lot of potential, but they went the wrong direction with this one
