I saw her on Will and Grace, and it just showed that she really can't act. It was way too forced. ( I did like her in "Desperately Seeking Susan" ).
Madonna is a diva- bitch who is too big for her britches. Do I like some of her music? yes. I just don't appreciate her holier than thou attitude. When she thinks she is losing popularity, she reinvents herself to satisfy the masses. She thinks she is way more talented than she is too. There are so many people with loads more talent then she. She's just really good at manipulating her image and the people that like her.
That's just my take on her. Cheers!
