Peter Sarsgaard, Isabelle Fuhrman, and Vera Farmiga in OrphanORPHAN

Director Jaume Collet-Serra's Orphan features that most indestructible and, oftentimes, luridly enjoyable of horror-flick staples - the psychopathic prepubescent - and would probably be a lot of fun if it wasn't so relentlessly unpleasant and stupid. Those of us who've been known to get a kick out of these Omen-esque outings will probably give the movie the benefit of the doubt for far longer than it deserves. But for all of its effective jolts and expert acting, Orphan is so frustratingly illogical that it trashes whatever goodwill you extend toward it, and the experience is too unremittingly dour and punishing to be any kind of not-so-guilty pleasure. (One of the friends I saw the film with left the auditorium saying, "I need a shower now." Get in line, pal.)
