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: [...]i said that it was good and fun but i was all wrong. the day i got it after playing with it by myself, it fell then the pet had a scratches and paint bruises (that white mark). the third day i got bored of the same three chips so i brought more, it was expensive and the chips are small. so my little sister already lost half of them (and the chips are easy to spot). the first two weeks it ran out of power, and it has their own special battery,so it was gone (also i forgot to say is the, gameplay of it was bad,and it was imposible to beat somebody with a higher level and better chips unlike yugioh). For kids (like me) don't ask to buy it ,it was hard to find some body with the pet. for parents make sure there is a x on this thing on your child's list,it won't last long (more likely for younger kids). overall to everyone should get the nintendo ds,GBA or atleat the video now thing, this pet is a waste.
Solution:
Negative
