I'm writing this one kinda late but might as well.
This Pilot was just great! It introduced us to the mind of our new Sherlock Holmes and gave us the cards that they are going to be toying with during the course of the show. If you didn't like it however, don't fret as the show does improve drastically later on.
I only have but two complaint and those are the lack of antagonists or just how quickly that is resolved once you've been introduced to the respective person or persons, and the lack of deductive reasoning by the observation of another person.
This show seems to focus a lot more on Sherlocks ability to view something and draw connections or research using his knowledge of said-thing. It's more like Sherlock knows a lot and that is the reason he's able to solve crime rather than being the deductive Sherlock that we know and love.
You haven't watched this show yet? What are you waiting for?!
