Apart from an obvious vehicle for Brown, I was unable to find any point to this tedious, poorly paced and poorly scripted film. The feminist message is as subtle as the clichés of Victorian England, strong-willed women and fourth-wall breaks that are regurgitated at the audience at every possible opportunity, to the point of tedium. Liberal reinterpretations and adaptations of Conan Doyle's beloved character can be and have been artfully and cleverly done, but the supposed sister of the legendary Sherlock and Mycroft in this version is simply a pretty martial arts dilettante who dabbles a little in word puzzles and relies on the gauche, predictable and transparent plot, rather than intellectual prowess or observation, to solve mysteries no more challenging than those tackled by the Famous Five. Her opponents are cut-out caricatures rather than anything against which she can really test her mettle. From a movie with a feminist message in 2020 I expect more than Mary Poppins with an uppercut and a couple of famous relatives. Nobody seemed to be comfortable with the script that lurched through a stilted pastiche of pseudo-Victorian English or in the sumptuous but unconvincing design. Superficially charming family viewing, but do not expect subtlety, humour, accuracy or intellectual stimulation.
