What the hell just happened? -10 stars !
17 September 2017 | by carjurosSee all my reviews

Utter garbage of a finale. It is as writer never hear of what Sherlock Holmes is about and just invented his own new character. I have not been this mad at the TV in a long time. Honestly just delete this episode it from Netflix. You should feel horrible for making such garbage TV.
