say what you will, BUT people don't get THAT famous unless they really really got something extraordinarily charismatic. And that's precicely what MJ has, unmatched charisma. He's the most entertaing pop dancer in the business, and he has a knack for creating catchy songs that don't sound like everyone else's stuff (Prince is able to do this as well). Though given his emmense popularity it is impossible for ANYONE to be in favour with EVERYONE, and that's just the nature of the biz.
With fame comes a lot of great rewards and a lot of people talking about you. Famous people who are successful realize this and MUST learn to accept it rather than trying to get people to stop talking about them. If you are going to be in the public eye, ESPECIALLY in the entertainment industry people are going to trash you, period. The bigger you are, the louder they yell, the more trash and lies they sling, the more they try to expose your truthful skeletons, and of course the louder your fans support you.
So, say what you will, he's not going to read it, and you're not saying anything too horribly original because MILLIONS of people all over the world have already stated an opinion one way or the other for several years.
