Question: Review: The musical performances here are quite dull. There is nothing wrong about them except that the musicians seem to be simply doing their job and nothing else. If I had paid good money for this concert in person, I would have been highly disappointed. The video quality is even worse. The DVD is cheap but not cheap enough to justify its purchase. 
 Polarity: Negative

Answer: True


Question: Review: What a disappointment. This book is about 50% self-centered travelogue and 50% teasers about the mysteries. I expected a book full of archeological information about cities and cultures that have long since disappeared, but instead got embarrassingly ridiculous chit-chat and superficial explanations. I wanted scientific information, not a book that tends to explain most of its mysteries via levitation and alien beings! 
 Polarity: Positive

Answer: False


Question: Review: As light weight sci-fi/horror anthologies go this is probably good value for money (given its low price), but the apparent lack of good editing and of proper proof reading is painfully evident and you definitely won't find any candidate for a Hugo or Nebula award.You'll find a couple of interesting ideas, a lot of trite and derivative ones and occasionally some baffling lack of coherent character development.There's enough to show that Messrs. Jason Brannon, Eric S. Brown and John Grover have the potential to write something good, but it seems to be, at the moment at least, unfulfilled potential. 
 Polarity: Negative

Answer:
True
