This is the book that began Gothic literature. Its interesting to see where it all began, but I can't say that it is exactly a good read. There is little by the way of characterization. There is both too much that is spooky in it and not enough. It feels a bit haphazard. Its very rooted in folktales and fairy stories and its interesting that the roots in Gothic literature are so clearly in that area. The fact that this novel created such a sensation shows how starved the public was for anything supernatural or spooky.
I suppose that it is worth reading for anyone who is interested in how the genre developed, but otherwise it is not really worth reading in itself. It's not exactly bad but a little dull.
