Elementary is a) the best Sherlock adaptation, and b) such an absolute delight to watch, 10000/10 do watch highly rec (ALSO has Lucy Liu dressed like this and come on COME ON)
Culturally, the only thing that dates Elementary is that they're shitty about fat people. They're even Delightfully Normal about Mrs Hudson, who's trans!
BBC's Sherlock was terrible, I never understood why people watched it. Moriarty was wretched, the worst overacting. Sherlock murders a guy, commits suicide, all good, right?
