‘Is This Thing On?’ Review: In Bradley Cooper’s Feel-Good Divorce Comedy, Will Arnett Is an Estranged Husband Who Does Stand-Up…as Therapy

It’s an observant, bittersweet, and eminently watchable movie, yet there’s an inner softness to it, a slightly pandering quality. Will Arnett, who has the look and demeanor of a less energized Michael Keaton, is likable enough in a slightly mopey way, but he has done a lot of sitcom work, and it shows. In "Is This Thing On?," Arnett seems, in essence, to play Alex as a sitcom dad — sharp-tongued yet benign, lost in his daze of self-interest, with an essential quality of harmlessness that’s the opposite of movie-star danger.
