Plot holes so big, even Mark Gatiss's ego would fit. This final episode is a grotesque mess of all the show's worst qualities. It is so enamored of its own perceived "cleverness," but there is actually nothing clever about the writing at all anymore. Sherlock may as well have a magic wand. A completely unsatisfying mess.
Now we come to an end. THE FINAL PROBLEM is a very good FINAL in the series. It doubled its mysteries, thrills, and it has a very surprising twist than last two episodes. In this episode, the storyline is becoming more interesting and intriguing. It's fun to see Sherlock Holmes, John Watson, and Mycroft Holmes in action together to fight the villain. Maybe, it isn't good as THE LYING DETECTIVE. But it is still good..
(1.5) Hopefully good riddance to a show that purposefully shot its leg by being flashily convoluted without ever giving smart or interesting explanations while patting itself on the back claiming that it's the smartest person in the room. It's sloppy, trite to the point of embarrassing (excluding the technical parts), self-indulgent, manipulating and unsatisfying in general.
I enjoy the 'Saw but questioning morality instead of arguing for it' shtick, but the episode wasn't particularly amazing otherwise. The whole Eurus plotline was a bit out there for me. And can't they just let dead people be dead, and not keep coming back for appearances?
