Probably the second best horror film made by Universal Pictures, after "The Bride of Frankenstein". It is melodramatic and not in the slightest campy. It is noteworthy for its lesbian slant (check out that scene with Nan Gray), and for having one of the first sympathetic vampires anyway.
Also interesting to note are the similarities to "Sunset Boulevard". Both involve a faded woman living in a decaying mansion with a manservant played by a director, and a doctor who tries to help the woman (in "Sunset Boulevard", of course, it was a script doctor). The similarities are so striking that it's hard to imagine Billy Wilder did not have this film at least partially in mind.
