Most sitcoms have done away with a studio audience but Not Going Out remains touchingly old-fashioned. If you're used to the natural feel of Gavin & Stacey or Outnumbered, it takes a few moments to acclimatise to the studio lights and set-up/gag/set-up/gag rhythms of Not Going Out, but it's worth it: the jokes are lovingly crafted and nobody could accuse Lee Mack of not knowing how to deliver a zinger. Mack plays hopeless big-kid Lee, whose long-held crush on his landlady Lucy isn't helped by the fact that she is the sister of his best friend, Tim (Tim Vine). Tonight's opener for series three undermines the trad format with a gleefully off-colour, not to say X-rated, storyline: Lucy thinks she's pregnant and Lee is worried he may have helped get her that way, although exactly how doesn't bear too much thinking about.
