I like Foyle's War. I think Foyle has a kind of smouldering sexuality. Midsommer Murders is just plain silly. More bodies than Friday 13th Part 65.
I agree Smurfy, there is a shortage of good TV dramas. Some of my favourites from the past have been:
Shine on Harvey Moon, The Biederbeck Trilogy, Our Friends in the North, GBH, Big Deal, The Gentle Touch, London's Burning and going back a long, long way - Within These Walls and The Secret Army.
I love a mixture of drama and humour - thus Dr Martin has been a recent favourite and Darling Buds of May a more distant one.
