Bill Murray is the only reason to see this film. His high energy and sensitive acting abilities take this cliche film out of the ordinary and give it the style that did not appear in the script or the direction.
Murray has been funnier and far more authoritative during his career, but he was never this joyfully floppy again. Meatballs is the crowning of his doofus glory and a great testament to his once improvisational appeal.
It's difficult to come up with a more cliche situation for a summer pic than a summer camp, where all the characters and plot turns are readily imaginable. That makes director Ivan Reitman's accomplishment all the more noteworthy.
For those of you that are big fans of the cult comedy hit Wet Hot American Summer, Meatballs is the summer camp movie it parodied the most, even though Meatballs had a bigger heart and was strictly PG.
