I've been enjoying the show so far. Good acting, fun storylines, it's a nice take on the character, and despite liking Guy Ritchie's films quite a bit, I enjoy the BBC take even more.
I too was drawn to the show because Steven Moffat (of Doctor Who) was writing the show. Now I'm hooked.
And I also recently noticed that Sherlock also had a role in Tinker Tailor Soldier Spy.
