Query: A Disappointing "Classic"

As I lifetime reader of science fiction I expected to love this book. Perhaps, being a noted classic, I expected too much from it. Honestly, it was all I could do to keep reading. The incidents throughout I found to be juvenile, predictable and extremely slow moving. It could be that sixty years of progress in the genre of science fiction has made this story seem old and all too familiar. For many of us old movies do not have the same "punch" that modern ones have. We have different expectations now. The same may be true with books.But it was more than plot that troubled me. I found the style of writing too weak to catch my interest. I still become captivated by the mood set by eighty year old stories by H. P. Lovecraft. This book by Heinlein did not captivate me in any way. Sorry, but I cannot recommend it.
