FarrierCollins’s review published on Letterboxd:
This was my first exposure to anything Sherlock Holmes related, so I went in blind and without any prior attachments. I can't say I was really taken by the story, but the light tone and Millie Bobby Brown's performance made it a fine watch. Specifically liked the fourth-wall breaks from Brown as that added a nice playful energy and certainly livened things up a bit. Overall, a cute and harmless movie.
