Leonora Anne Mint’s review published on Letterboxd:
The first of these old-timey Sherlocks that I've seen to really feel like it has much bite or personality AND not contain anything really cringey. The fact that people have been "modernizing" Holmes for a tremendously long time is really underscored in these films where he has to foil various Nazi plots, and the inspiration this takes from the real-life fascist radio propagandist "Lord Haw-Haw" is a fascinating intersection with history. There are some lovely dramatic close-ups and chiaroscuro images, and it just feels like a bit more filmmaking was involved. Still a pretty basic story, still in the realm of being the type of cozy low-brain-energy movie I fall asleep halfway through and finish up the next day, but with a bit more spice.
