I've never seen it before, but I've heard nothing but good things about it, and the cast is a pretty solid one, so for £7.95 (or less with a Walkers/15% code/Quidco), it's more than worth a shot :)
"Golden Globe® and Emmy® Award winner Tina Fey writes, Executive Produces, and stars as Liz Lemon, the head writer of a live Variety programme in New York City. 30 Rock also features Golden Globe® winner Alec Baldwin (as corporate executive Jack Donaghy), Tracy Morgan and Jane Krakowski (as Lemon's unpredictable stars Tracy Jordan and Jenna Maroney) and Jack McBrayer (as the naïve NBC Page Kenneth Parcell). Co-workers and friends are all trying
to balance work and life, with the inevitable result of failed relationships, disastrous parties, at-work drunkenness, hard-core
coffee addiction, world-class sandwich eating and occasional attempts to chop down Christmas trees. Join in the behind-the-scenes hilarity with the complete first and second season on DVD."
