As Corman says himself on the audio commentary, the movie really holds up. You have to cut it some slack of course and you'll probably see the "matte" effects for example. And then there is the wonderful Vincent Price - plus a story by Edgar Allan Poe. The latter is probably something you are aware of anyway. And while I have seen a few adaptations, I've never read the story itself. Of course Roger Corman added some things story wise - some things may not seem to make much sense, but that can also be the beauty of it.
Also Corman deliberately chose to make the movie/story seem out of this world. The acting overall (even more so by Price - by choice) is borderline theatrical. And I don't mean that in a bad sense at all. You may have to wait for the thing you are watching this for ... but when it comes it is quite well done. A spooky story with a neat twist, that is not over explained, even though it may be a bit flawed if you actually think about it. But it doesn't really matter. Costumes and set design are top notch, so there things that really elevate this.
