Scary Movie 4 (2006)

The sort of movie you like in spite of yourself, Scary Movie 4 is obvious and dumb, but it possesses such a giddy, good-hearted spirit that even its terrible jokes (and there are tons) get by on something resembling charm.

This a rapid-fire romp through "War of the Worlds," "Saw," "The Grudge" and "The Village," cut up into skits and pieced back together in some mutant jigsaw puzzle with a few pieces missing, delivers a barrage of low-minded gags with high-spirited energy.

There are plenty of chuckles at the expense of Dr. Phil, Shaquille O'Neal, Carmen Electra, Charlie Sheen and series stalwart Leslie Nielsen. But with no comic carryover from one skit to the next, true belly laughs are few and far between.

And as ever, the jokes are a jumble of the gross, the baggy, the raunchy, the mistimed, and - every once in a while - the refreshingly incorrect.

The humor emphasizes quantity over quality, but the batting average isn't too bad. And where else can you witness Leslie Nielsen do a nude scene?
