Heston Blumenthal, of triple-cooked chips fame, is a mad food scientist. Well, that’s how we’re introduced to him in Heston’s Marvellous Menu. Tonight’s BBC Two programme had a rather theatrical premise: a chef recreating the complete dining experience (menu, team, decor, diners) from a pivotal year in their restaurant’s history.

All the TV networks like to big up their news journalists as major players, but are they as important as they like to think?

This three-part series by historian Lisa Hilton is a follow-up to her previous effort from last July, Charles I: Downfall of a King (BBC Four).

Christmas and Agatha Christie are a very good fit – how better to spend time with your loved ones than sitting down to watch some murder and intrigue together?

Alibi is usually your one-stop shop for re-runs of Father Brown or Death in Paradise, so well done them for commissioning this new murder mystery. It comes with a glittering pedigree, having been created by actor-turned-writer Amelia Bullmore (Scott & Bailey etc) and bestselling crime novelist Val McDermid, but despite a cracking cast it struggles to pass the credibility test.

The appalling fate of the allegedly unsinkable liner Titanic in 1912 has fuelled endless feature films and documentaries, not to mention a dismal drama series by Julian Fellowes (there was also a proposed Titanic II vessel which would have been built in China, but which remains mysteriously un-launched). However, it’s difficult to see why this film has appeared 107 and a half years after she sank.

In films, as in life, unreliable narrators are not hard to find. But there is something remarkable about the unreliable narrator of Elizabeth is Missing, BBC One’s newest feature-length drama. Its protagonist, Maud (Glenda Jackson), is unreliable in the extreme – confused, forgetful and emotionally wounded. Yet unlike most unreliable narrators, we never fear that Maud is trying to sell us a false story. She is so clearly fighting to understand the truth.

Happily, Joe Barton’s tinglingly original thriller (BBC Two) finished as smartly as it began, not by any humdrum tying-up of loose ends but by giving free rein to the story’s ambiguities and impossible choices. If indeed they really were choices.

“Restorative Justice Practitioner” sounds like a euphemism for a Mad Max-style lone avenger, but in director Anna Hall's devastating film for Channel 4, it was a woman called Kate whose job was to bring together conflicting parties and help find a resolution.

Who can explain the mystery of the solitary wolf who has taken up residence on an archipelago off Vancouver Island – the Discovery and Chatham Islands to be precise – and has developed his own unique hunting methods while patrolling his self-contained personal turf?
