The stuff I've really enjoyed this year so far would be as follows-
Stewart Lee's Comedy Vehicle
Genius
That Mitchell and Webb Look Series 3
Michael McIntyre's Comedy Roadshow
Charlie Brooker's Newswipe
I have to say that it's been a good year so far. Besides the shows above I've found a lot of other good stuff that I've enjoyed, and while there's been some obvious duds as well I don't think there have been as many as in previous years (although there is still time for that to change). Comedy is certainly not in the terrible state that everyone has been talking about recently.
