Despite a prolific career, Rose Byrne—who’s done turns in comedies (Bridesmaids) and alleged comedies (The Internship) before—is mostly known for the law drama Damages and as The Underwritten Pretty One in films far and wide. In Neighbors, she gets no help from Andrew J. Cohen and Brendan O’Brien’s script, but at least director Nicholas Stoller (The Five-Year Engagement) lets her keep her Aussie accent and her keen wit, and as a result she matches Seth Rogen beat for beat the whole way. Girl is a comedy genius. Byrne is Kelly, a new mother and homeowner married to Rogen’s Mac. When a frat led by Zac Efron moves in next door, the marrieds—going through a quarter-life crisis, presuming parenting negates partying forever—make several attempts to just be cool before resorting to an infiltration slash takedown. Efron’s performace is also a nice departure—his Teddy is sensitive and understanding, not your typical ’80s-style frat bro—and Stoller directs with an infectious flair. It speaks to the quality of a movie like this when the funniest jokes come from relationships, not dumb shenanigans (though it has its fair share). Neighbors is a surprise and a delight.
