Catastrophe, 10.00pm, Channel 4

Sharon Horgan and Rob Delaney are back with the fourth season of their hit dramedy, which had turned rather dark by the end of the third season.

Things came to a dramatic head after Rob's secret relapse to alcoholism ended in a les-than-sober car crash and a forced confession to Sharon, just before the cops arrived.

A new acquaintance becomes increasingly friendly with Rob, while Sharon dabbles in a new hobby that could also see her on the wrong side of the law.

They've come a long way since this:
