What did you think of Siddhartha by Herman Hesse?

I recently read this novel, and I know it is a favorite for many people. Personally, I expected a bit more and wasn’t as impressed. So I want to know what lessons/morals you got from that book, why it appealed to you etc. Did it make you think deeper about certain issues? If so, why and how?

So in a way, I want you to give me your evaluation of the book.

Note: I am past the age where I get to read novels for “school.” So this is not homework, I read this book for personal curiosity and I am asking this question for the same reason.
