One is when the Jonas Brothers (in the story their band is called Connect Three) deliver their song “Play My Music” to the assembled campers, showing the verve and stage presence the film’s other performers lack.

It’s a sort of glass-ceiling character for these movies and shows either the writers of such stuff think that young viewers can’t handle anything more than blatantly obvious good-gal/bad-gal dynamics, or they have no idea how complex and varied real high school social life is.

Also at the camp is a vain rock star (played by Joe Jonas) doing some image rehabilitation, as well as that insufferable diva (Meaghan Jette Martin). Mitchie (Demi Lovato) is desperate to go to a rich-kid rock ’n’ roll camp, but her family can’t afford it until her mother gets hired as the camp cook, entitling Mitchie to a discount. The movie has some bright spots, but so much of it revolves around the resident diva of the title camp that it’s hard to focus on the good stuff you’re too annoyed at having this lazily imagined character shoved down your throat for the zillionth time.

Some hacker needs to go to work on the Disney computer that randomly mixes the same 10 plot lines and 15 young actors to create new movies and television shows.
