The show began with a lot of potential but it didn't quite live upto the mark. The season 4 especially was the worst ever. The hype of Moriarty being back pulled you in but it ends up being nothing! The reboot of Hound of Baskervilles is an example of how an amazing story could be mangled. Literally, Sherlock's mind runs through these random words until he comes up with some H.O.U.N.D project name off of some obscure connections that only his mind can make. The audience cannot observe his brilliant deductions and inferences as they never get a glimpse of the context or a perspective of the evidences that Sherlock observes.
