Mr. Gilchrist is a friendly, somewhat tentative screen presence, but Craig has enough intelligence and humor to be both an agreeable central character and a charming guide to life in the adult psych ward. (The teenage ward is closed for renovation). He has a morose roommate named Muqtada (Bernard White), and a chorus of would-be mentors, the most important of whom is Bobby, a soulful, scatterbrained schlemiel played, it is almost redundant to say, by Zach Galifianakis.Why would Scott feel the need to make such snide remarks about Galifianakis when apparently he is good in the movie? And I really don't see why he feels the need to insult Jonah Hill. Or is he insulting filmmakers who use him? Or us for liking it? Or society for quickly changing our preference for "tubby comic sidekicks"? The review is perfectly fine without this bit that adds exactly nothing to our understanding of the film's quality.
Mr. Galifianakis is everywhere these days — the most in-demand tubby comic sidekick since the heyday of Jonah Hill, which I guess was about six months ago. Mr. Galifianakis’s Gleasonesque movements and deadpan, behind-the-beat timing serve him well in this role, as does his ability to seem completely in earnest even when his actions and utterances are bizarre or nonsensical. Bobby is credibly troubled, neither a holy fool nor an over-the-top goofball, and his moments of wisdom are as believable as his bouts of instability.
