Everything you would expect from a cookie-cutter Seth Rogen bro comedy is in “Neighbors 2: Sorority Rising” (2016). There’s weed. And male genitalia. And dildoes (Or is that dildos? Paging Mr. Quayle… Mr. Quayle?). And it’s all so derivative until the one or two scenes that make you laugh out loud and then the $1.60 you paid at Redbox doesn’t seem like a waste. (You spent $12 to see it in a theater? Poor dear.) Anyway, sequel, partying girls instead of partying boys, hijinks ensue, blah blah blah. And an oddly fascinating subplot involving Zac Efron’s character arc. Say whut?
