Decent start to a new series. Freeman and Cumberbatch were solid and seemed to fit well as a team. Kept enough nods to the classic versions while updating it to allow for the 21st Century.

The on screen leads to the clues were a nice touch and I preferred them to the CSI flashback trick that is now used too often elsewhere. Not quite as well used as in Zombieland but good nonetheless.

Script was solid but nothing special. A lot of the supposedly clever plot deductions were a bit telegraphed. And they have started off with the ever predictable TV staple of using the only other identifiable cast member as the bad guy which was only slightly offset by not showing him to the camera until after he was identified.

Gatiss writing himself in as Mycroft is at the very least disappointing and potentially long-term damaging. His screen presence is weak and he doesn't fit well in the character. Also have to wonder; after the weak series of Dr Who if Moffat/Gattis really have the time and skill to deliver both these series at the quality required.
