Nicholas Stoller's Neighbors flexes the same kind of comedic homoeroticism that has made wealthy men of writer / director Judd Apatow and his stable of actors, principally Seth Rogen and Jonah Hill. Though Apatow is not formally associated with this picture, the doughy Rogen stars along with the adonic Zac Efron as the neighbors of the title. Rogen and Rose Byrne play new parents living the American Dream in a college town when the Delta Psi Beta men and their coterie of busty babes move in next door. Rogen's Mac and Efron's Ted become quick "bros" but then after too many late night frat parties and a call to the local constabulary they declare war. Once the barrages of penis jokes, simulated (and actual) intercourse and references to ejaculate are unleashed, there's no turning back. And for the audience you either go along for the ride or cover your eyes and ears. Perhaps it is true as some have written that once you've passed through the dense cloud of sex and drug references you will discover the film's deeper message about maturity and responsibility. I can't attest to that because Stoller has dialed the outrageous meter up to 11 and the quiet pillow-talk between two stoned parents tagged on the end just seems a bit, er, anticlimactic after 100 minutes of unspeakable vulgarity. Recommended but not for youngsters or oldsters who can't take a joke.
