Seth Rogen and Rose Byrne play a married couple with a new baby and a new house. Everything is idyllic until a fraternity moves in next door. When the couple calls the police, the frat boys, led by one unruly chap (Zac Efron), wage a war of pranks on the couple. Schlubby man-child Rogen and handsome youngster Efron have more chemistry than Rogen and Byrne do, and the clumsy series of penis-and-pot gags lead to an ending that doesn’t feel earned, but it has laughs, is slightly deeper than you may expect, and passes so effortlessly that it’s over before you can chant, “Toga! Toga!” Rated R. 96 minutes. Regal Stadium 14, Santa Fe; DreamCatcher, Española.
