Lawrence is lucky he looks and acts like an overgrown 12-year-old boy -- that's how his floppy-body, rubber-face antics manage to reach deep down to the juvenile inside and, once in a while, yank out a chuckle before you even know wazzup. Sure, Blue Streak has gratuitous wacky characters (pizza-delivery guy with buck teeth and ugly jogging suit) and a few too many instances of "BAM!" and "Ka-POW!" in Lawrence's dialogue. Then again, nobody claimed this was the thinking man's movie.
