It's 'psych0' . . . the teenage years!
What was Hitchcock's deranged psycho like when he was a teenager? That's the question posed and answered by Bates Motel (Universal), in which Norman is persuasively played by Freddie Highmore and his domineering mother by Vera Farmiga, who was so good as George Clooney's lover in Up in the Air.
She's very good here, too, and also very scary – whether politely seeing off hopeful schoolgirls who call to the door in search of her son or butchering a rapist neighbour who invades her home and attacks her.
That happened in the clammy and unsettling first episode and I'm not sure how the story will proceed, but it certainly won't be The Little House on the Prairie.
