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

New input: The advetising on the box caught my attention so I bought this playset for my son's birthday. It was a complete waste of money! The toy design is terrible! The batcave falls over when played with. The elevator doesn't function properly either. Because of all the malfunctions and collapes, my son lost interest within five minutes of play. If you want your child to have a Happy Birthday or Merry Christmas go with something other than this toy.
Solution:
Negative
