re: Sherlock Season 4 (Spoilers)

Indeed.

While I was not blown away by season four I have to say I am most impressed with the performance of Sian Brooke as Eurus. She stole every scene she was in, and while her character's arc ended up disappointing, I have to say that she did not. That scene where Sherlock meets her for the "first" time in her cell was incredible. You could literally feel the chemistry between the two actors and I found myself unable to look away from her eyes. They were very captivating.

As a villain, even with her mutant-esque powers, she had Moriarty topped until the final ten minutes or so. The writing turned her into a stereotypical lost soul and that gravely disappointed me.
