Thanks to Youtube, the trailer/documentary for Elementary is doing the rounds.
The thing that screams out for me is that while BBC's Sherlock is clearly written by two people who know the Canon - Elementary is written by people who at best have (or appear to have) only a passing familiarity with it or, and this is arguably worse, have good knowledge of it but have chosen to ignore everything that doesn't suit them. Is this driven by a desire to avoid comparisons with Sherlock (if so mission failed) or a desire to avoid any legal moves from the Sherlock team (after all Steven Moffat did say he'd be watching)?
Whichever it is, the show (based admittedly only on a trailer but a trailer is supposed to make you want more) comes across as a bizarre cross between House and Crocodile Dundee (the latter thanks to the fish out of water element of the - pardon me Sting - 'Englishman in New York' encountering cultural as well as social hurdles.
It looks like it will be entertaining in the same way as RDJ's cinematic Holmes is. People will watch it and enjoy it but they will, at the same time, acknowledge that its link to the source material is, at best, tenuous. Holmes has suffered worse at the hands of screen adapters and will endure this but I think, after Sherlock, we've come to expect more.
Oh, by the way, a tattooed Holmes? Come on, seriously! He wrote a monograph on tattoos. It didn't mean he'd have one.
