But I have dabbled my feet in the paddling pool that is Elementary, and...it's kind of a weird experience; there are some facets of commonality between it and Sherlock (and the half hour of the first RDJ movie that I vaguely watched but had my attention more on my iPhone so gave up), some obvious differences...some areas where I wish they'd had at least a stab at making a nod to the mythos (for example, they could have called Sherlock's liaison at the NYPD "Lestrade" - although I hadn't realised until now that Aidan Quinn's character is at least named after a character in the Conan Doyle novels; they could have given Sherlock a landlady called Mrs. Hudson; they could even, at a pinch, have invented a fictional New York street called Baker Street for Sherlock to live in, ideally at 221B), but it's still fairly entertaining, mostly in proportion to the extent to which it just about steers clear of being a routine crime series.
Thing is, though, I was watching the fourth episode - Rat Race - yesterday, and I found myself laughing out loud at the Sherlock snark. I think this is what I'd found lacking (or at least not quite as obvious) in the earlier episodes. I note it's written by a guy called Craig Sweeny, who hasn't written any previous episodes and isn't listed on Wiki's entry as writing any later ones (although it only lists up to episode 8 so far). I hope he does do some more, because it really was terrific fun. I'm looking forward to watching the next couple of episodes too, as one of my friends has squeed rather enthusiastically about 5 & 6. :-)
Oh, and if/when Elementary decides to introduce Mycroft into the series, could he please be played by Benedict Cumberbatch? :-)
