The main problem with Rey Mysterio's run with the World Heavyweight Championship is how horribly they booked it. It had a great start with his match against Orton on background... then there was his feud with JBL. Why did Rey Mysterio lose to The Great Khali and Mark Henry right after winning the title? Mysterio should of beaten Henry and never had a match again Khali.
What kind of a champion loses to a midcarder in his first few weeks?
