I'm only half way thru S1 and this is a very entertaining show with a great cast. Mark Strong is such an understated presence and Carice van Houten, well, she's just gorgeous to look at (she doesn't even need to speak) and such a talented actor. Loved her in GoT too. It's interspersed with some quirky humour, often supplied by the very likeable Daniel Mays. One to watch.
