Someday, scholars will compile the definitive canon of Comedies About Weddings That Go Very Wrong, and this film, from Jake Szymanski, will warrant inclusion. If you’re a fan of the genre — especially in its more ribald and R-rated forms — this should deliver some laughs this summer. That’s not to say that it’s especially good, or in any way original, but it hits its marks: nudity; lots of sex jokes; decent supporting actors (Kumail Nanjiani, Stephen Root); an attractive setting (Hawaii); a dance number; and a — ahem — happy ending. The premise is pretty basic: Two hard-partying immature brothers (Zac Efron, Adam Devine) need to find “nice girl” dates for their sister’s wedding, and post a request online. Two hard-partying immature besties (Aubrey Plaza, Anna Kendrick) see the ad, and fake being “nice girls” for the free trip to Hawaii. You can write the rest yourself, though I did appreciate the twist that the women were “worse” all ’round than the guys. It’s a film that at least offers equal opportunity in comedic vulgarity for men and women, so there’s that, #feminism.
