Birds of a Feather: TV review The other reason - and a major explanation of why the show was such a hit in its heyday - is the natural chemistry between the two lead actresses; they are entirely believable as sisters. In last night's episode, the estranged siblings - Sharon (Quirke) was back living in her Edmonton council block and Tracey (Robson) was still ensconced in her Chigwell mansion - bumped into each other at a book signing; author "Foxy Cohen" was signing copies of her erotic bestseller Sixty Shades of Green. Spotting her bedraggled sister at a bus stop, Tracey took pity and offered her a lift home - a visit to Sharon's dingy flat allowing for the first of several lines with a recessionary flavour. "David Cameron says we're all in this together," said Sharon. So how comes I haven't seen him down by the bins? Hardly side-splitting, but, increasingly, inequality could prove a pointed sub-text for writers Laurence Marks and Maurice Gran. The signs are however that any such observations will take a distant second place to some bad puns ("wee" and "Wii," for pity's sake) and the sisters' familiar put-downs of Dorien. Indeed, having reassembled the household - "Foxy Cohen," it transpired, was Dorien's nom de plume and a writ for plagiarism engineered her reinstatement as Tracey's house-guest - it remains to be seen how Marks and Gran will take their sitcom forward. Brash, moneyed and Thatcherite Essex was culturally relevant when Birds of a Feather first aired in 1989, but, after 10 series of The Only Way Is Essex, the milieu has long since morphed into a cartoon parody. Perhaps Tracy could run as a Ukip councillor or Dorien, in an act of charity perhaps designed to win the approval of handsome young men, open a food bank. Don't hold your breath. It's easy to see what's in it for ITV in reviving one of the BBC's most popular shows of the 1990s - there are few of the risks associated with starting something new, like Vicious or The Job Lot. And it's not impossible to revive a sitcom if it's done with intelligence and an eye for time passing, as Dick Clement and Ian Le Frenais demonstrated when they moved The Likely Lads forwards after a break of seven years with Whatever Happened to the Likely Lads?. But if Birds of a Feather becomes as hermetically sealed as Tracey's triple-glazing, my guess is that we'll tire of this threesome soon enough.
