Query: Zero stars, that does it!

STUPID. This has so many mistakes. There is no such thing as Cinnabar. It's Cinnamonbar. You called "Iland" "Island!" It is stupid to make such a horrible guide. The cover is stupid, the information inside is stupid, and even the people who say 5 stars or four-and-a-half stars are total IDIOTS!The author rushed and didn't care what he wrote. This guide stinks! It has every mistake I cold imagine! I recomend the Prima! That guide has everythink! This guide does not have a complete Snotedex. The Prima has a Pokedex. Prima rocks!'Tendo is the worst guide. Don't buy this, you nag!
