I finally watched Episode 1 of Sherlock last night!
I was almost completely unspoiled, other than glimpses here and there of people's fantastic LJ art inspired by the series, and knowing it's a modernized version. Even though I'd seen art depicting John and Sherlock, I couldn't get used to Sherlock's appearance! Wow, he's so unusual looking.
Me: "He's so insufferable! How could anyone stand to be around him?!"
Husband: "Of course. He's Sherlock Holmes."
Also, I immediately KNEW!!!!! the "arch-enemy" was Mycroft! He was just so Mycrofty. (I kept quiet until it was revealed, though. I'm not obnoxious like Sherlock. ;-)
Loved Lestrade too. And the music, which was SO much like the music from the movie! MOST OF ALL, John and Sherlock have amazing chemistry.
I really enjoyed it, and I think my husband did too, although he had to pause it several times for me to explain things (it was a lot easier for me to follow, being familiar with the original story) and to translate what they were saying. The accents were a little challenging.
