Released this week: An American Haunting, Monster House, Nacho Libre, Slither.
Monster House: This film uses motion-capture software to turn live-action performances into children's-storybook animation, and the result is charming, albeit scary. A trio of suburban kids launches an assault on a house that gobbles up anybody who crosses over the property line.
Nacho Libre: Jack Black has his moments as a friar/cook who longs to be a Mexican wrestler, but the shtick seems a little forced. Black being pummeled by his opponents is pretty much all there is to the plot, but the movie nevertheless has a pleasantly strange vibe.
