Haven't yet seen "Elementary." I know one acquaintance loved it but a friend didn't so I'm not sure what to think. But I do want to give it a fair shake . . . when I get back to WI.
My reaction: generally I liked it.
The mystery was pretty clever, fairly decent deductions despite some far-fetched deductions (who transfers 5 yr old pictures from their old phones? A lack of old pics isn't suspicious; it's normal.) The phone location was a nice touch, and I like how they worked in details from Study in Scarlet but with modern touches. Yes, they seemed to be borrowing a bit from BBC-Sherlock but I think (hope!) that will dissipate as the writers hit their stride. Plus the first official we meet is Gregson, not Lestrade. I will be very happy if there's a Youghal or Macdonald in the future. :D
I'm really happy with this new Sherlock. For the first time in 20 years, we have a Sherlock who's not a completely arrogant prat deserving a hard punch in the face! This one actually has some tact, and gives a flip about other people's feelings, and apologizes. O.O Excellent! . . . now stop mumbling half and show some consistency in your use of American/British slang, and this girl couldn't ask for more. (Although I'm hoping Watson's deduction about Sherlock's life in London missed the mark, because cliche and lame much.)
I still hate the name "Joan Watson" but Lucy Liu didn't do quite as bland a job with the character as I'd feared. And honestly, I like the Watson-with-a-history take on the character. I also like the lack of siblings for her, something new. (But I'd like to hear the backstory as to why an obviously Asian woman with obviously Asian parents have such an Anglo-Saxon last name.) And I really like that she's intelligent from the get-go. And in this ep, at least, she hits a good balance of being a side-kick and of keeping Sherlock in line . . . but we'll see how well that keeps going.
So, yes. Overall I'm happy with the episode, it's not entirely a pale copy of BBC, and I hold out hopes for the rest of the season.
