It's a classic for a reason. Brilliant characters, engrossing drama with the added benefit of interesting political, theological and philosophical sections.
How can you not love something that constantly refers to people as scoundrels and sensualists? I may even start running around labelling people scoundrels for the most trivial things myself. It's too good of a word to be used sparsely, although I might not be able to pass off calling people sensualists, as unfortunate as that is.
