“Breaking Legs” (*1/2 out of four) was a plastic pastiche of “Mean Girls” and “Footloose” about a small-town high-school girl (Liv Southard) who finds nowhere to fit in except the school dance team where she proceeds to fall in love with the boyfriend of the main and mean vindictive cheerleader (Alexa Sutherland) and runs afoul of her clicky team of friends. Guess what happens next. Formulaic and predictable enough to insult anyone’s intelligence and missing the clever sting of the two aforementioned teen movies. John Hughes made movies like these in his sleep in the ’80’s.
