BORN TO KILL, C4, 9pm

LAST week’s opening episode got off to a very slow start and felt at times like a drama for teenagers. Was this going to be a dark, psychotic version of Hollyoaks?

We spent far too long last time establishing that young Sam is damaged and sinister in some unspeakable way, so tonight we finally get to see some progress in the story. All those scenes of him creeping around the hospital wards and rehearsing a persona in the mirror were starting to get a tad repetitive. Wisely, we move on.

The death on the geriatric ward is provoking some concern but will anyone suspect the polite schoolboy who gives up his time to read to the patients? Certainly, one of the nurses, Cathy, had suspicions about him last week, questioning why he was always hanging around the ward and not out with his friends like a nice, normal boy.

And Sam’s mum has to face her terror and tackle the big secret she’s been hiding from Sam all these years. I wouldn’t dare bring him any bad news, would you?

LOCKED UP, C4, 10pm

STAY with Channel 4 for more drama but for an abrupt, and welcome, change in tone.

This is the second series of the Spanish drama about a young, naive, middle-class woman who’s been jailed.

Last time around we saw Macarena try to recover from the shock of a prison sentence and adapt to life in a tough Spanish jail, and the series ended with her being involved in an attempted escape. We know such attempts in TV land can never end well. The inmates can’t escape to Brazil for some plastic surgery and a job in a pub as they’ve got a rollicking story to uphold so they’re normally bundled straight back to prison.

Macarena is a reluctant escapee, having been hauled into the plan against her will.

How will this band of angry, panicked women survive on the outside when they have the cops on their tail?
