“Undercover Cheerleader” (*1/2 out of four) was a slapdash melodrama about a transfer student (Kayla Wallace) who goes undercover at her new school to expose the cruel cheerleader culture but doesn’t realize how much trouble and difficulties she is in for and how this will affect her social life. Just a series of ideas from other and better movies repackaged and rewritten. Any one scene from “Mean Girls” or “Clueless” tops this hands down.
