Query: One of the most worthless pieces of literature i've read--

I have to say that i do love to read a variety of books, but Sinclair Lewis' novel Arrowsmith was absolutely horrible, and discouraged me from reading any other novels by Lewis. The novel was dull and boring. There was no excitement or suspense. There wasn't even a interesting plot. The novel also had an extreme amount of unnecessary characters,and it was too long which made the novel even more ridiculous. From most novels, you learn some values or something, but I didn't learn anything from Arrowsmith, except that sometimes a nap can be more interesting than reading a book.
