I was weaned on horror movies and love them inordinately, but the genre has gone to the dogs — and to the muscle-bound werewolves, hormonal vampires, flesh-eating zombies, machete-wielding psychos, etc. It's also depressing how most modern horror pictures have unhappy nihilist endings in which everyone dies and the demons pop back up, unvanquished — partly because studios think happy endings are too soft, but mostly because they need their monsters for so-called franchises.

Director Ang Lee has a surprising affinity for the Indian hero of Life of Pi — that's his name, Pi, and he's seen at several ages but principally as a 17-year-old boy adrift on a lifeboat in the South Pacific. He's the lone survivor of a shipwreck that killed the crew, his family and a variety of zoo animals his father was transporting to North America for sale.

Actually, Pi is the lone human survivor. He shares his boat and its dwindling food supplies with a man-eating Bengal tiger.

The best thing about David O. Russell is that he cultivates his disequilibrium. In Silver Linings Playbook, his hero is disturbed and his heroine possibly more so, and his other characters have a grip on reality that is only marginally more secure. Russell might have made them seem the dreaded "q" word — quirky — and OK, he does, a bit, at the end, which broadly conforms to the rom-com template. But until then, Bradley Cooper's Pat Solatano is someone you'd be less likely to dream about than get a restraining order against.
