A scene from Neighbors 2: Sorority Rising.

The first half of Seth Rogen sequel Neighbors 2: Sorority Rising is as funny and snappy as the first movie—but the film loses its way a bit by the time credits roll. Still, if you are looking at laughs per dollar, Rogen and Zac Efron deliver your money’s worth.

The spin this time out has a sorority led by Shelby (Chloë Grace Moretz) moving in next door to the Radners (Rogen and Rose Byrne). Shelby is determined to party like a fraternity does, and this leads to a semi-depressed Teddy (Efron) coming on as the sorority’s mentor. This restarts Teddy’s war with the Radners—which is bad timing, because their house is in escrow. It’s during this stage of the film when it is at its nastiest and its best.

When Teddy joins forces with the Radners to destroy the sorority, things get a little misguided. The film has some of the funniest dialogue of 2016 (“Sometimes you have to suck a bunch of dicks to find out you don’t like sucking dicks”), and I’m always down for Rogen’s humor. Byrne is an undervalued comic actress, and Moretz fits right into the stoner mode. Efron gets the biggest laughs in the movie, even when it starts to get a little too busy.

A gag involving those ever-pesky airbags is killer-funny, as is another visit with the dean (Lisa Kudrow). As sequels go, this isn’t great, but it’s a worthy installment.
