The Hound of Baskervilles (1939)
Pretty weak, compared to pre-code Hollywood mysteries and compared to the book, which was itself a little uneven. I guess that's because it's mostly British with Basil Rathbone being the lead as Sherlock Holmes.
The book review, crosspost:
I like mysteries pretty decent and I like pre-code Hollywood movies, so I've read and watched a lot of Dashiel Hammett, but have actually never read or seen anything except the very common and popular culture references of Sherlock Holmes e.g. pipe, hat, Baker St., "Elementary, Dear Watson", etc.
So I picked up and read this and it was pretty decent. Reminded me of good mix of late Victorian literature (a little Frankenstein) and Romanticism (Edgar Allen Poe/Goth/Rue Morgue).
All in all, I enjoyed how it was written, very sportingly and articulated as I guess you'd wont from an 1890's English gentleman but even in small doses the arrogance of Holmes is overbearing IMO
