Slapdash filmmaking and a thick, indolent haze of self-satisfaction most characterize Grown Ups, Adam Sandler’s new ensemble laffer, which rounds up a bunch of old costars and offscreen pals and serves as an informal reunion of Saturday Night Live alumni. A few fitful flashes of interpersonal ribbing interrupt what is otherwise a wan, meandering tale, which warms over hackneyed bromides about familial engagement and ladles those over thinly sketched characters and stock banter galore. Predictably, the actors just each yawningly trade on their own well-worn personas. It’s air-quote comedy, with all the make-a-buck calculation of a rock ‘n’ roll reunion tour.
