“A true event.” Read on for the critics' full verdict on last night's TV.

Law and Order, BBC4
“Compulsory watching for television genealogists, I would say, but pretty good watching even for those who don't give a damn about ancestry and pedigree.”
Tom Sutcliffe, The Independent

Law and Order, BBC4
“A true event.”
Andrew Billen, The Times

Gary: Young, Psychic and Possessed, BBC3
“Watching people pretending to channel spirits is always excruciating, and this was no exception.”
Paul Whitelaw, The Scotsman

Mistresses, BBC1
“I might as well own up to the fact that I haven't been in a steady relationship with Mistresses since about three episodes into the first series. Last night was just one of those meaningless one-night stands that occur so frequently in the drama itself. It meant nothing, honestly, and I won't be doing it again, a promise I hope to keep because last night's episode was the last of the current series. It ended in a welter of Mills & Boon wish-fulfilment.”
Tom Sutcliffe, The Independent

Holloway, ITV1
“Holloway is obviously Bad Girls. It's just as good, with the same mix of tragedy and comedy, and strong female characters. Maybe the story-lines aren't quite as exciting, but then it does have the extra piquancy that comes from it being not made up.”
Sam Wollaston, The Guardian

Horne & Corden, BBC3
“I did a bad thing during Horne and Corden. I'm sorry, and if it's any consolation I'm not pleased with myself. But I laughed [ ...]I'm not proud. It didn't happen again in the rest of the show, hasn't happened in either of the previous shows, won't happen again, I promise. They're still a couple of plonkers.”
Sam Wollaston, The Guardian
