I like Elementary. I don't look at it as a continuation of the Sherlock Holmes stories (and I've read them all), but I like the common sense "pay attention" theme. (And I really enjoy watching with my son because it helps reinforce the whole "look at the details and use logic" theme that I'm trying to instill in him.)
BTW, the staff writers are on Twitter and sometimes live-tweet during the show (East Coast time zone).
