This was definitely the best season so far of series. The first season was terrifically silly, but finding its feet, the second had some absolutely brilliant over-the-top moments, but was uneven, I don't think this season had a bad moment. They took the nerds out into the world more, to great effect, and Moss' character (Richard Ayoade), in particular, really settled into a great foil for Roy (Chris O'Dowd), continually bringing up the most inconvenient details out at the most inconvenient times. Douglas Berry as Douglas was actually funny this season (not so much Season 2). The ensemble sparkled.
Over here across the Atlantic, there was a thankfully aborted attempt to transplant the show, dropping at least Pansy Parkinson, who, I think, is a consistently brilliant comedienne. Her deadpan and timing are flawless. British comedy is best done by Brits. And Irish. And Scots. Ok, and anybody who was brought up with British weather and boiled food. Or whatever the secret is.
The standout episodes, if there had to be any, were "Friendface", "The Speech" (In which the guys convince Jen that a black box with a red light they've thrown together IS The Internet) and "Calendar Geeks", but, again, it was solid season all around. Thanks Graham Linehan.
