I’ve been watching Elementary, and I figured out why I subconsciously keep expecting Sherlock to relapse: because his drug addiction registers on Writer Brain as Chekhov’s gun, and therefore I expect it to go off eventually. But at this point (halfway through season three), I suspect that’s the point the writers want to make. An addiction is Chekhov’s gun . . . and you have to live the rest of your life with it sitting on the mantel, begging to be fired. Whether this is a suitable analogy for addiction or not, I can’t say — I have fortunately never struggled with that myself — but I’m pretty sure that’s the thematic point they’re aiming for. Which I do find interesting.
(What do I think of Elementary as a whole? I think I would like it better if it weren’t a Sherlock Holmes adaptation, because I often find it disappointing in that regard. Their Moriarty is fabulous, but sadly underused, and their Mycroft was not just a resounding disappointment but an active detriment to the story as a whole. But where it’s doing more of its own thing, I think it’s decent. Not hugely compelling for the most part, but acceptable background entertainment.)
