It entirely depends on personal taste, but I remember enjoying Cold Feet from 15 or so years ago, This Life a series from the I think the '90s about aspiring 20/30 somethings sharing a flat, Bleak House, The first Damages and the first Broadchurch, subsequent ones not so good imo, Brideshead Revisited, Life Begins, Cracker. I've started watching an American legal drama, The Good Wife which I'm enjoying, also The Affair now on the 2nd series which has just been released here. Probably loads more I've forgotten about.
