Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: Just writing this to provide moral support for anyone who reads this book and is thoroughly underwhelmed.Asimov's prose is clean but his tone seems uneven in this installment, as opposed to the tighter first book.The book is essentially two disconnected adventures... not very appealing.There's a female character in the second adventure that's quite problematic; she's dull, and Asimov spends a lot of time and effort on the fact that she's (gasp) not male.Finally, this series feels very dated, in terms of language, attitudes, and even vision of the future. "Nuclear" is the buzzword; everything's like the '50s, but nuclear-powered.I liked Foundation but Foundation & Empire tends to wander away from the idea of the Foundation as the main character, and instead can't seem to decide whether to focus on galactic-level events or protagonists. This would be excusable if the protagonists were interesting.Go read Jack Vance or Gene Wolfe if you want masterful sci-fi!
Solution:
Negative
