One of the greatest comedy sequels ever made.

Neighbors 2 never lags, and the laughs keep coming, even though they’re coming from a fairly familiar place. If that’s all you want, that’s what you get. But, hey at least you get it, which is more than you can say for most sequels.

The film has a knowingly conflicted engagement with millennial-generation feminism that freshens its outlook even as it unevenly rejigs many of its predecessor’s gags. Still, while a subtly clawed Chloë Grace Moretz proves a worthy new foil, it’s Zac Efron’s tragicomic anatomy of a dudebro that remains this series’ sharpest asset.

At its best, the film becomes something winningly subversive.

Bad Neighbours 2 is a smart and worthy continuation of this comedic battle of the age-groups with a cracking takedown of "super rape-y" frat boy culture, where every themed party is 'bros and hoes', and makes a stand for female empowerment, all the while serving up belly laughs, rehashed-but-still-brilliant airbag gags and feminist-inspired gross-out acts.

It’s got just about enough laughs, but there’s so much more that the Script by Committee wants to shoehorn in, like female empowerment, bad parenting passed off as “doing our best” just like our parents, gay marriage and the incredibly sexist college Greek system, a relic of the “Animal House” era that remains as “rapey” as ever.

This pretty routine follow-up has some decent material and amiable bad taste, heavily diluted with gallons of very ordinary sequel product: more of the same.

In their awkward attempt to shoehorn these kids into the first pic's formula, Stoller and his writing collaborators care far less about creating believable characters than getting to the next laugh.

Neighbors: Sorority Rising turns out to be an uneasy watch, awash with unconvincing performances, unfunny stereotypes, and dubious gross-out gags.

Like most comedy sequels, it’s also content to dig out the same old punchbowl and dilute the dregs.
