Q: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Asimov had some interesting concepts in this novel. It's unfortunate that he killed them with his stale characters and unbelievable plot devices. The book (and its successors) read like an episode of Leave It to Beaver set in outer space. The repetitive vault openings became tediously predictable - I felt like I had read the same chapter a dozen times. Read the Cliff Notes, save yourself some time. *****
A:
Negative
