I don't think that you are the only one who doesn't like it, maybe just one of the few who has verbalized it. Let's face it, that book is on almost every reading list written.
I remember reading it the first few times and thinking, why do people like this book? Although, I get the rhythmicity of the book, it always seemed boring to me personally. However, we read it many times and looking back on it, for really young kids, it is a great way to expand their memory and have a sense of reading themselves by having them finish some of the sentences. My son used to love to do this, my daughter not as much. He is a strong reader and she struggles more. I am not sure if there is any correlation, but interesting nonetheless.
