For an 90-minute farce about the battle between an upwardly mobile young family (Seth Rogen and Rose Byrne) and the principled sisters next door who refuse to hold off partying during a 30-day escrow because partying is their whole darn raison d’etre — they started the thing because regular sororities aren’t allowed to host their own blowouts and must venture inside horndog frats to get their drink on — this sequel to the cheerfully sweet n’ dumb original sure does tackle a lot of issues. There’s feminism, natch, because these women gotta fight for their right to party. But there’s also loads of unrelated anxiety about being a parent: the two year old’s favorite plaything is Mom’s vibrator, and her baby sister is on the way! And also about growing up and finding your way in the world: when former frat king Zac Efron’s old bestie — out and proud and also engaged — asks him to move out, Zac finds he’s a hot hunk of lonely manboy. It might have worked if everyone involved had maybe cared a little more (Efron, at least, commits) and/or tied everything together, but instead, we get dangling ball sacks and breech baby feet, pointless Holocaust jokes and the declaration that throwing bloody tampons is both funny and empowering. Oh, and vomit. Still, the cartoon-style scramble over a garbage bag full of weed at a football tailgate is kind of a delight. With Chloe Grace Moretz; Nicholas Stoller directs (2016) — Matthew Lickona
