I loved some of the older stuff produced by Hat Trick productions - things like Drop the Dead Donkey, KYTV, Chelmsford 123.

Waking the dead is quite good. The whole series of Prime Suspects was utterly brilliant. Bread was another good sit-com.

I'll also echo the other scribblers' suggestions too - especially The Second coming, Wire in the Blood, Blackadder, Father Ted etc, and I didn't know the Red Dwarf telemovie was going to be out so soon *ggg*
