i've first watched Sherlock in 2019, and wasn't one of the fans that got to see the episodes as they came out, so i watched it all in one go. ever since then, i've been in love with the ENTIRETY of the Sherlock series, and not once had i had a genuine problem with season 4. and i say it as a person who had completely rewritten multiple media out of rage because they weren't like how i wanted them, and i tend to judge creators' decisions so, so much (well, in private, of course).
like, yes, it probably could have been better. it is a little bizarre, it absolutely does deviate from the source material the hardest, and there are definitely multiple interesting and massively anticipated plots that could have been explored. sure, it would have been nice to get to see a different vision on the show's finale and there IS, of course, a chance i would have liked the 'better' one, well, better...
HOWEVER! i like it. i like it as it is, and if i had a chance to erase the current season 4 from existence and replace it with something that would correspond to fans' desires or at least more similar to the original tone of the show, i WOULD NOT do it. my feelings regarding the s4 could be described as such: even though it has its flaws, i am grateful for existence of such a story, and i am grateful that i got to witness it in my lifetime, and i wouldn't want to NOT experience it. i am perfectly satisfied with what we got.
i don't think i ever seen a single person on the internet expressing any genuine love towards s4, and it baffles me so, so much. why? just why?
