Query: Life of Pi

I read this book for a book discussion club and I didn't like it even a little bit. Every time I stopped reading this book and closed the covers, I felt like I had to wash my hands. It could have been a great book, but in my opinion it wasn't. The ending made no sense and I always feel cheated if the ending is stupid after all the time I spent reading the damn thing!
