I've still not got around to watching it yet, but I'm told by reliable sources that this show is hilarious.
So £6.49 for the first two seasons is an excellent price for it :)
"In its first two seasons, 30 ROCK earned a boatload of trophies: the series won well-deserved Emmys for Outstanding Comedy Series (both years), and snagged accolades for both its lead and guest performances. Set behind the scenes at THE GIRLIE SHOW, a fictional sketch-comedy series, 30 ROCK follows show-runner Liz Lemon (Tina Fey) as she contends with her program's infantile stars, Tracy Jordan (Tracy Morgan) and Jenna Maroney (Jane Krakowski), trades barbs with network exec Jack Donaghy (Alex Baldwin), and makes ill-fated attempts at a personal life. This collection includes every episode from the show's first two series."
