Even s3 while much better to watch than e2
Essentially makes Sherlock a murderer - a master brain needs to murder - so essentially he isn't so good after all? Moriarty killed himself and Sherlock killed the other criminal he couldn't outthink.
I enjoyed the series thoroughly for entertainment and will watch s4 - just don't think it was masterful.
P.s dr Watson finally seems to have come on his own in the final episode.
