Bah. I think not.
First off, she CAN sing. She was on
Star Search (and sung quite well, I might add) at the age of something like 8...and you can't accuse Ed McMahon of being blinded by her gonzagas, either, because she was as flat as a board back then.
True, there are people less successful, but more talented, than her...but that doesn't mean she is without talent. It means she has talent, and has maximized it through marketing. She has plenty of things about her to dislike (ain't much of a role model, in my opinion, for example)...but don't let her faults convince you that she has no virtues. Hitler was a smart guy...just because he did horrible things, it doesn't mean we should, say, claim that he was not an impressive leader. Obviously he had virtues...and acting as if he had none simply because he had glaring faults doesn't make any sense.
Besides: logically, the extremes on these issues are almost NEVER right. It's no better to claim she's talentless than it is to claim that she's the greatest singer alive. She's got talent...I don't see how anyone can deny that. A lot of what she is is marketing, but it's not 100% smoke and mirrors.
That's how I see it, at least.
