More than anything, he's earned his way to his spot, via WCW, and was one of WCW's few bright spots towards the end.
The fact that he went from being the 'future' of WCW, to WWE's job boy, is what people don't like, and it's a case of Booker working WWE style - I imagine you just haven't been able to see what the rest of the IWC have in his career.
And i'm not even a fan of the man.
