Very unlikeable character which seemed like a cookie-cutter cutout of his last role as the con-artist Kanji Senkawa in the Emi Takei drama "Ima kara Anata wo Kyouhaku Shimasu"... hope this isn't going to be his signature role type.
Reminds me a bit of Actress Yuko Takeuchi, who not only has also made a career out of playing these snarky type geniuses as well (most recently in the drama "QUEEN)...
...But ALSO played yet another "Sherlock" type character in her HBO/Hulu series "Miss Sherlock" a few years back!
Funny, seems like in these Japanese dramas, all you need to be "Sherlock" is to be an unbearable blowhard...and play the violin at some point!
(Well, in Yuko Takeuchi's case, a cello, but ya know what I mean)
So strange, seeing as how neither of these dramas are meant to be the actual Sir Arthur Conan Doyle character Sherlock Holmes, just loosely BASED on 'em-why have them playing the violin anyway? LOL, It's like the writers were like, well, he/she's like Sherlock, so he/she HAS to play the violin.
Oh, and make sure to have your "Doctor Watson" type character as well. I liked Shihori Kanjiya as the "Dr. Wato" supporting role (Well I admittedly have soft spot for her anyway)...
...but having a harder time with Takanori Iwata as the Doc sidekick...not really compatible at all.
In fact, I wish they cast Maho Yamada (who appears in the Fujioka show as a police assistant) in the role as she's far more charismatic and "Watson-ish, IMHO.
Ah, Benedict Cumberbatch, what have you wrought?
PS: Out of all the incarnations, Cumberbatch, Downey Jr, etc, my favorite was and is STILL the Disney animated version "The Great Mouse Detective" which to ME is the perfect portrayal of Sherlock: Aloof Genius, Trusted Partner, and even a Man (mouse) with a Heart.
Also the perfect Watson! Yep.
