Well I watched but really I think they just used the Sherlock name to hook the story in the public mind.
Why didn't they just write it as a straight series and leave out the SH references?It would have worked just as well if they had worked at it.
Kinda fed up with the way some people don't have the courage to just be original..
When people bother to do so it can work very well,Being Human is a prime example.
