|Leonard Maltin/Plot synopsis:
Promising film speculates about Conan Doyle's detective when he was a boy, introduces him to Watson, and involves him in his first great case. Knowing references to Holmes's later life, perfect Victorian atmosphere all give way to jarring 1980s special effects, inappropriate INDIANA JONES-type subplot, and action climax that doesn't make much sense. If you do watch it through, be sure to stay through the very end. Written by Chris Columbus; Steven Spielberg was an executive producer.
