Cory Enns’s review published on Letterboxd :
One of my favorites of the Frankenstein films, and also seems to be the heaviest influence for Mel Brook's Young Frankenstein. I believe this was the last gig for Karloff as the monster. From here on out the part was played by Chaney Jr, Lugosi and Strange. Beautiful sets and lighting give the film odd dreamlike qualities that feel like a noir film.
