Started to watch this but the tone put me off. I think it is directed to a Tween audience. Too many clean faced girls in ragged cloths. Poor, poor pitiful me. It's Penny Dreadful w/o the fantasy, adult subjects and artful acting. Reminded me of the New Adventures of Huck Finn, if anyone knows that obscure reference. But that at least elder program held steady pacing.
Was expecting this to be maybe Charlies Angels. Holmes comes on at start of episode, or Watson as Bosley, gives an assignment and an ensemble cast tries to discover the one small part to answer Holmes question. e.g., How many people in London smoke New Curry Tobacco. What I watched was not that. It was misdirected kids, all races and great teeth.
Spiteful, back sass, juvenile modern kids and too many set scenes borrowed from familiar movies. Not that whimsy isn't fun, but this isn't that either. It's boring.
