I dunno, ugly is as ugly does. Gerard Depardieu is attractive to me... especially in his earlier movies, such as (wait, I'll be back with names) movies he was in with Patrick DeWaere. Man, he could move.

Be forewarned, it ain't nice about women. Or men either.
There's one more I'm remembering, will try to find that too.

Ugly has more to do with personal ickyness, as others have said. A lot of magnetic personae didn't have, uh, classic features, for example, Yves Montand - see him in Z and then try and call him ugly. I am remembering a friend who always kiddingly talked about her boyfriend, he of the classic features, as though his perfectly honed face was something he needed to fix. Besides, eyes win out over a lot of other attributes. Eyes and the brain behind them.
So, I think Michael Jackson is homely, but also think he is a sick fella, whatever the truth of accusations against him.
