★★★ (3 out of 4)
There are so many devilishly clever things that director Guy Ritchie packs into “Young Sherlock” that I don’t know where to start enumerating the joys in this Prime Video surprise package. Let’s start with the fact that Ritchie eases up on his patented action overkill to examine Sir Arthur Conan Doyle’s master creation in the exhilarating act of inventing himself. Doyle purists may faint dead away at the liberties being taken and dared here.
