John le Carré's 1993 novel The Night Manager was his first post-Cold War effort, and the fortuitous setting of its early scenes in a hotel in Cairo has allowed TV dramatiser David Farr to move the action forward from the post-Thatcher fallout to the 2011 "Arab Spring".  Here we encountered the fastidiously tailored Jonathan Pine, the titular night manager of the Nefertiti hotel, a man who keeps his head while all around him is panic, gunfire and explosions.

Perhaps the BBC didn't need to make W1A, its new self-satirising sitcom. In the clerical comedy Rev, the Church of England could be considered a very serviceable metaphor for the Corporation, with its unfathomable layers of bureaucracy, well-meaning but slightly pitiable niceness, a self-image that belongs to a forgotten century, and self-flagellation before other cultures. Though the BBC does have rather more money to spend.

Those of us who regarded The Office as a work of comic genius (not a word I use lightly) will, I'm afraid, take some convincing about Stephen Merchant and Ricky Gervais's latest offering. Keen fans who have followed the duo's every move since that landmark sitcom will feel they know every last trope on display in Life's Too Short, from its mockumentary setting and unPC subject matter to dark comedy and celebrity guest spots.

It doesn’t often happen that a new sitcom is born perfectly formed. The Royle Family, it was instantly clear, would do no wrong. And there was nothing much the matter with those things by Ricky Gervais. (I'd also make a case for The IT Crowd.) But maybe Rev has a harder trick to pull off. Unlike comedies which achieve their effects by formal daring, Rev operates within narrower strictures. It is in all essential respects a deeply traditional sitcom.
