Zac Efron, Rose Byrne and Seth Rogen reprise their roles for this, a tired and unnecessary sequel to Bad Neighbours that rehashes its plot, with a sorority as the noisy neighbours instead of a fraternity.. In order to ensure their house sells, Mac (Rogen) and Kelly (Byrne) turn to old enemy Teddy (Efron) for help. Cue predictable trickery in which both sides attempt to outwit each other to varying degrees of success and crude gags that feel stale. The script – written by no less than five male screenwriters – pulls focus onto female camaraderie in a neat expression of feminism, yet can’t help but undercut this with stupid stereotypes. Chloe Grace Moretz takes a decent stab at showcasing her comic chops as lead sorority Shelby, while Efron nicely changes up his turn as the now outdated frat, who can’t stop living in the past. It’s a shame, though, to see Byrne and Rogen shunted somewhat, the former in particular, who’s more than proved herself capable of killing it before.
