Radio Times review

If Stella's episodes had titles, this one would be Time Bomb. The ticking before the explosion (a fling being discovered) becomes almost deafening. "Midlife Crisis" Michael (Patrick Baladi) is the culprit, playing away with barmaid Beyoncé. His live-in lover Stella is oblivious - though hospital consultant Mr Honey seems to be making a play for her.

The escalating chaos of a party for Michael's daughter Katie takes our mind off things - and the karaoke turn of the birthday girl herself (take a bow, Martha Mackintosh) provides the kind of show-stoppingly sweet moment that Stella does so well. We could do with more of them. Former Welsh rugby star Scott Quinnell puts in another brief but caustic cameo.
