For a film about a foursome of millennials behaving badly, Jake Szymanski’s comedy Mike and Dave Need Wedding Dates (B) gets gold stars for laughs and even a heartfelt moment or two. Zac Efron and Adam DeVine play troublemaking brothers known for making other peoples’ weddings all about themselves with their stag antics. Their attempt to reform by bringing sensible dates to their sister’s Hawaii nuptials leads them to partner with Anna Kendrick and Aubrey Plaza, who prove to be an even more devious duo than the dudes. It’s a hoot to see Kendrick play against type, and all four lead comic actors hold their own with fast-paced lines and pratfalls. At times both profane and poignant, the film is often too much of a good thing. It’s sometimes tough to follow the film’s moral compass as it’s progressive in a few ways and a bit backwards in some others. The physical comedy is pretty hysterical throughout, and it gets its share of signature gross-out moments. A summer lark packed with pleasures, it’s a successful descendent to funny fare such as Dirty Rotten Scoundrels, Romy & Michele’s High School Reunion and Wedding Crashers.
