This anecdote from Walter Iooss is pretty bad:

LeBron became a villain to many after The Decision. I've seen a lot of entourages, but none like his. In July 2010 I got an assignment from Nike to shoot LeBron right after his TV special announcing his move to the Heat. We rented the Los Angeles Memorial Sports Arena, where the Lakers and the Clippers used to play, and there were 53 people on my crew-including hair and makeup artists, production people, a stylist. I had $10,000 in Hollywood lighting. It was huge. When LeBron arrived, it was as if Nelson Mandela had come in. Six or seven blacked-out Escalades pulled up, a convoy. LeBron had bodyguards and his masseuse. His deejay was already there, blasting. This for a photo shoot that was going to last an hour, tops.

This is how crazy it was: I wasn't even allowed to talk directly to LeBron. There was a liaison, someone from Amar'e Stoudemire's family. I would say to him, "O.K., have LeBron drive right," and then he'd turn to LeBron and say, "LeBron, go right."

LeBron had guards in the portals on the mezzanine level, talking into their hands. Really, what was going to happen? And then at the end of the shoot they all got in the Escalades. My God, I've been around Michael Jordan, but with him nothing even came close to this. Unimaginable.

But, he seems to have grown up some since then. Of course his childhood was obviously less than ideal. Hard to judge people from unstable backgrounds thrust into fame and fortune.
