I really loved the show. I love Sherlock and John's friendship, caring for each other. I also loved Mrs. Hudson, Una Stubbs. Sadly, she left us. I also loved Eurus. She was a very smart character and had a dark secret. I almost cried, when Sherlock hugged her and forgave her. In season 1, Sherlock was cold, rude. In season 4, he became a kind, generous, caring man for everyone. Love and respect for all the actors played in the series. Most for Mr. Benedict Cumberbatch and Mr. Martin Freeman.
