One of my favorite books is Good Omens.
It would be hard to do really well as a movie/TV series, but there is always hope. (I feel the real quality is in the language and the feel of the writing, more than the story itself. Which is probably true of many good books from people like Terry Pratchett and Neil Gaiman.)
In other words, the bulk of the humor comes from the language in what the narrator says, not simply what's happening. This is even more true with Woodehouse books, which is why the books are so much more funny than the movies/episodes. "The smile disappeared from his face like mist from a razor blade" is not easy to transfer to film. Unless they include a narrator, maybe they should.
