Seriously good fun of the rom-com suspense sort. Introducing the young, as in Young Adult fiction reader population, to the finer points of the British mystery novel/film genre must be done with careful planning. It is important to engage the subject of your efforts, but not bore them. You also need to not be overly obvious in the expositions of plot, character, mis en scene, costume, motivation and the usual essential and the occasionally esoteric concerns. Let me be frank. In the late 1980's, no less a talent than Steven Spielberg took a shot at a fancilful failure with the title Young Sherlock Holmes. I will be brief. Spielberg and company tried too hard, took the Conan-Doyle oevre a bit too seriously and over produced not so much of a dud as an overwrought, overthought anachronism with clumsy special effects that were most likely out-of-date when they were pitched as the next big thing to the production and design teams.
Enola Holmes 2 has several things going for it. First, clearly someone on the production team knows the Spielberg film and is committed to not making the same mistakes. Second, this production team is in for the long haul. They got a lot of the kinks out in the first film, given their roots in the house that Warner Brothers built for Harry Potter, the long view is the only one that matters. And, as the Brits have taught us repeatedly, long term production planning is a high art. Best to make the sophmore effort something to be anticipated and written home about. This one lacks for nothing.
So there is everything we think we know and should expect about a Sherlock Holmes knock off, except one of the main haracters is the great detective's formidable kid sister. Yes, there is the feminist thing going on along with the multi-cultural thing and if that's not your cuppa, tough. Now if you are operating on the old school principle of entertain the audience well, you have come to the right place - adventure, romance, mystery, intrigue, a plucky young woman , a loyal brother, derring do and all sorts of villainy. The Americans and the Brits (and the French, the Italians, the Chinese, the Spanish, hell even the Germans and the Norwegians) have been making delectable bits of entertainment telling the same versions of the same stories since the 1890s. Glass Onions anyone?
I think Enola has about three more features although I would throw in a 5 or 6 episode limited series maybe as a finale to flesh out a few things. I had a lot of fun with this and will now track down the 7 Per Cent Solution which along with Agatha and Gosford Park are three films that took the literary who done it adapted for film to wonderful places.
