If you like watching slashy pretty men being jerks and are fine with the erasure, dismissal, objectification and mistreatment of anyone who isn't white, straight, male, upper middle class, English, and able bodied, then this is the show for you. Well, episodes 1 and 3 are, episode 2 is just bad all round (and
amazingly racist).
I...found parts of it interesting and engaging, and the slashiness is of a particular type I quite enjoy, but on the whole it wasn't as clever as I would have liked and large sections made me very annoyed.
Meta: Neoliberal Holmes, or, Everything I Know About Modern Life I Learned from Sherlock gives a very damning critique, but to follow up on the portrayal of Watson's disability in particular: it is NEVER MENTIONED AGAIN. At all. Not even vaguely alluded to.
And "That's the way it was dealt with in the books" doesn't make it ok, that just means it's not inaccurate
as well as ableist. If they were doing a totally 100% literal adaptation which followed every minute detail exactly as it happened in the books I might forgive them and blame Arthur Conan Doyle, but they weren't by a long shot. They chose to keep that particular flaw of the books and must bear the responsibility for that choice.
