This is a very enjoyable read, sort of a cross between Raiders of the Lost Ark and Star Wars.Clearly many of the negative reviewers here have a personal agenda to push. If L. Ron Hubbard had published under a pen name, there would be very few negative reviews. Some of them obviously never even read the book.The film based on this book was very badly done. Don't let that sway you.If the author's reputation bothers you, put a piece of tape over his name or something. This is a fun, easy read.And yes, I am very familiar with classic Science Fiction.
