Along with Insomnia and the inexplicably-unreleased Death To Smoochy, this eerie thriller serves to rehabilitate Robin Williams. His cloying wacky zaniness jettisoned, he's a broody bugger as the middle-aged loser who becomes obsessed with a cute family whose holiday snaps he's developed for years. Like a chubbier Travis Bickle, he feels his fantasy figures owe him emotional payback. He freaks, rivetingly.
