The gleeful, stunted-maturity idiocy at the heart of Adam Sandler’s Billy Madison and Happy Gilmore and Andy Samberg’s Hot Rod is the target at which That’s My Boy, their new comedic collaboration, is aiming. Unfortunately, if a wild, anything-can-happen philosophy permeated those delightfully warped offerings, the same thick, indolent haze of self-satisfaction that characterized 2010’s Grown Ups, Sandler’s previous latter-day nadir, is manifest here, in a laboriously programmed vulgar comedy of air-quote outrageousness.

Director Sean Anders, who in 2008’s Sex Drive delivered as fun, lived-in and casually assured a teen sex comedy as since the original American Pie, here serves as a pace-master and little more. There’s no frisky independent personality to this tale, only an inexorable slog from set piece to set piece, and scenes written to seemingly fold in as many friendly cameos as possible.
