Sherlock

 The 2015 ? Christmas special has just finished and I have to say it was quite good... However I had sussed who the murderer was from pretty early on and why the murders where being committed, less obvious was why Moriarty was in it, and why the story jumped back and fro in time.  It was like a confusing episode of Doctor Who.
 And another thing, I thought the Beeb were not supposed to use the name Sherlock Holmes any more after a lawsuit?
 Being honest I think having it set in the 1880's is far better, it's as the books were written for a start, all the high tech nonsense just spoils it.
