Vacation Friends is a droll and mildly salacious flick that revels in subverting the expectations of its central characters and, eventually, its viewers.

There’s nothing especially revelatory about Vacation Friends. There are a few genuinely good laughs to be had involving drugs, golf and a catamaran, both during the vacation and the wedding. And there’s some tedium during the inevitable falling out segment. But it’s enjoyable in a way that doesn’t make you think about lost time and experiences over the past year.

Clay Tarver, a veteran of the TV series “Silicon Valley” (and a founder of the postpunk band Chavez) directs with an eye and ear that’s a cut above what one usually gets with this sort of fare.

Vacation Friends does earn a fair share of guffaws with its familiar mix of R-rated raunch and feel-good sentiment, and it’s lightly amusing to see the well-cast players breathe a satisfying degree of fresh life into a predictable scenario that recalls “Mike and Dave Need Wedding Dates,” “What About Bob?” and a dozen or so similarly contrived comedies.

The talented quartet saves the movie, but making it great would take a rewrite.
