I really enjoyed the fact that the wrestlers were split between males and females, and compete against each other without any difficulty. I am completely unfamiliar with professional wrestling, so don't know if this is true to form. It works out particularly well when a little known rule comes in to play during the Big Chew's match with Werewrestler!
Including Ollie's struggles in school, and problems with his best friend, ground this somewhat goofy fantasy with some realistic problems that many middle grade readers face. I wasn't entirely sold on the fact that one wrestling match would save Slamdown Town, but since the owner was an egomaniacal caricature, it just added a level of silliness to the story.
Readers who understand the world of professional wrestling will certainly enjoy this romp, but I can seeing being popular also with fans of Patterson's I Funny or Zach King's magic Trilogy. The energy and level of goofiness is about the same.
