As played by Bullock, Gwen is an alcoholic in denial whose latest bender with boozer boyfriend Jasper (Dominic West) ruins the wedding of her sister (Elizabeth Perkins) and lands her in a month-long rehab program with the requisite gang of struggling drunks and junkies. Newcomer Alan Tudyk steals his scenes as a gay German rehabber who might've dropped in from a Berlin performance-art exhibit, and Steve Buscemi aptly conveys the weary commitment of a counsellor who's seen it all. Thomas has surrounded Bullock with a sharp ensemble, and the addition of singer-songwriter Loudon Wainwright III (as a kind of Greek chorus crooner) is sublimely inspired. Certainly no surprises here--the warring sisters will reconcile, and at least one rehabber will fail to recover--but there's ample pleasure to be found in Bullock's finely tuned performance, and in Thomas's inclusion of flashbacks and tangents that add depth and laughter in just the right dosage. --Jeff Shannon, Amazon.com
