I was a fan of Great Khali in WWE. He was one of the better "monster" heels in the past decade, and he did his job as World Champion in 2007.
Did he put on classic matches weekly? No.
Did he fly off the top rope? No.
Was he supposed to be do any of those things? Absolutely not!
The Great Khali was build up as an unstoppable man, who couldn't be beat. That was his character, and it worked perfectly (for a year or two). Here are my favorite matches from his WWE career.
