This started out very promising (the highly skilled and resourceful secret organisation), became complete and utter bullshit (turns out the secret organisation isn't that skilled or resourceful or influential at all. I mean, their Wi-Fi password is "Dracula" and some sleazeball of lawyer can can just waltz in and get Dracula out? Are you fucking kidding me???), made some questionable plot decisions and somehow managed to arrive at a rather satisfying ending. This show was all over the place and I don't know how I should find it. But clearly Moffat had lost his mojo for some time now. The last through and through good thing he wrote was Sherlock's "The Abominable Bride".
