I just thought it was boring.
And the movies are worse.
They dont actually make a point, they tell a relatively uninteresting story from a terribly uninteresting point of view.
If they were trying to say something, they failed.
Uh... it does say something. The problem is, the message, while it may have been powerful during the Gilded Age, is something many many many books, films, and songs have covered since then, and so it doesn't have the same impact. Mind you, it's not one of my "favorite" books, and not something I would heartily recommend to most people, but there is definitely something you can get out of it.
And just by seeing the preview for the new movie, it seems like they went overboard with fancy sound effects and whatnot, but that's not what the movie is about. The movie version starring Robert Redford will always be the classic, and the only one worth recommending.
