PAUL BLART: MALL COP seemed to me, from the trailer, horribly stupid and simple. It seemed like one of those films where the only funny parts were in the trailer. Well, it's not, and it's a great family comedy that will leave everyone in stitches.
Language consists of several "a*s"s and one "go to hell". There are some mild innuendos, but no sex. There is the threat of violence and mention of "silencing" hostages and "putting a bullet in your head". Fortunately, all the on-screen violence is comic (pratfalls, stunts, etc.).
This is a great movie, highlighted by the clever script and Kevin James's performance as Blart. He's a great guy; a hero you can root for, and his on-screen adventures come without much objectionable content.
