I think it's sad, he was such a troubled soul.
I can remember as a kid watching the Motown 25th reunion special on tv and seeing Michael and his brothers perform. The brothers left the stage and then Michael played the new stuff, Billy Jean. He did this incredible sideways moonwalk and everybody in my house couldn't believe it. The next day at school, EVERYBODY was talking about that performance. I'll never forget it.

How about watching the world premiere of his Thriller video on MTV. It might not seem like a big deal now, but at the time he was doing things that other artists had not even thought of.
You don't have to like the man, but you can't deny his talent back in the day.
