Previously on Sherlock: Sherlock went on a massive drug bender and staged an elaborate case to catch a serial killer, all so that he could give John someone to rescue and somehow help him process his grief over his wife’s death. It turns out that Sherlock and Mycroft have a heretofore unseen secret sibling who, surprise, is actually a sister, not the brother everyone thought . Her name is Eurus and she’s a little bit…well, crazy is probably the best word. She staged an elaborate ruse, involving multiple disguises and fake identities to both pose as John’s therapist and also as the woman who managed to get him to engage in an emotional affair. Why? No idea. Oh, and she also pulled out a gun and shot him at the end of last week’s episode.
Man, a lot of weird stuff happened this season. If you need a recap of last week, you can catch up on "The Lying Detective" here.
“The Final Problem” is, like much of Season 4, a mixed bag. There are several intriguing smaller riddles, along with a few plot threads that make absolutely no sense. (And one rather large plot thread that makes no sense either.) The insertion of Eurus in this story still feels strange, and at times too new to hang the crux of the season on. And, for better or worse, the show officially seems to have crossed the line into pure soap opera territory. There are a few twists and character moments that would probably make Days of Our Lives’ infamous Stefano DiMera proud.
