Direct quote from A Study in Scarlet: "Holmes was certainly not a difficult man to live with. He was quiet in his ways, and his habits were regular."
And yet nearly every adaptation (especially the more modern ones) play into the 'arsehole genius' trope and make Holmes a bad housemate.
I cannot accept 'bad housemate' Sherlock. Not when the first conversation he ever has with Watson is when he ensures that they compare habits to see if they'd be a good fit for sharing a flat.
When adapting Sherlock Holmes, I can only accept one of two things:
Holmes is genuinely a good housemate, or
Holmes is weird as hell, but there's something equally wrong with Watson to the degree that Holmes will be doing science experiments with poisons in the kitchen at 3am and all Watson does is glance at it and go "ah such quiet habits, I'm so lucky to have found such a good and reasonable housemate".
