It depends what you like; ie are you a crime buff like myself? Or do you like the more suspenseful ones like Jekyll? Honestly, anything with Moffat is great! :D

For comedies, I love The Brittas Empire, Keeping Up Appearances and of course, the famous Blackadder (I'm excluding the ones you've already mentioned above).

For mystery/crimes, I confess to being the only I know who like Taggart. I am also big on Silent Witness and Wire in the Blood.

There is North Square, which starred both the guys from Whitechapel ages ago. I don't know if it's anywhere on the net but I saw it on TV ages ago. It's about life in a solicitors firm.
