!!YMMV tropes in this work include:

* CrowningMusicOfAwesome: Dear heaven, the ''score''. It is orchestral, epic, and ethereal.
* VindicatedByHistory: It's now considered one of Creator/BillyWilder's best, and many consider it the greatest movie about Sherlock Holmes. Creator/MarkGatiss creator of ''Series/{{Sherlock}}'' considers it the best and cites it as an influence on his take on the character.
* TheWoobie: Holmes. Early on, Watson overshoots his bounds with a question about Holmes's past, and Holmes, previously in decent humor, gets cool and goes to his room. Later on, the man himself tells Madame Valladon that his fiancee died just a day before the wedding. He seems to have gotten over it, but the fact remains that he was ''that'' close to getting married once. The end simply tops it off, and ''Watson'' isn't about to deny him his cocaine.
