No joke is too crude, too lewd or too simple-minded in co-writer-directors Jason Friedberg’s and Aaron Seltzer’s anything-goes — and I do mean anything, good, bad and just plain silly — spoof of last year’s sword-and-sandals actioner 300. I admit, with considerable embarrassment, I laughed quite often. But then, how could anyone completely hate a movie in which a Simon Cowell lookalike is pitched into the Pit of Death?
