I like the current Sherlock - the cast is brilliant!
I am a huge Top Gear - there simply is no better car show!
I like Luther - his dark and gritty being plus the funny serial killer friend is a nice touch!
Death in Paradies - Love it! (new season just started with a sad event but I am already satisfied with the "replacement")
Inspector Barnaby is great fun!
Lewis is a great movie series too!
I like a lot of British shows simply for the reason that there isn't exploding shit every 30 seconds and there is no "PewPew, I shot the car and there it goes into a fireball" bullshit all the time like in most American shows.
