Beiderbecke, Very Peculiar Practice, Edge of Darkness are but three series from the 80's which combine a dry, sometimes ironic, humour with social comment. You won't laugh out loud like you would with Morecambe and Wise, Tommy Cooper etc. but this humour is equally valid. I guess I would call it satire. The central character of Dr Daker, an innocent in a world of almost Smiley like intrigue, is played with perfection by Peter Davidson. But then a lot of the other characters are played so well, I think this is why these sort of series work so well. The second series was even more weird, a bit like the later parts of Twin Peaks, but I still look forward to its release. I wouldn't expect this to work for all people but it certainly works for me.
