I'd add song selection to the list -- she kept trying to be a Mariah/Whitney style "diva", but she is much better suited to a more husky/vamp style. Ertha Kitt or even Marilyn Monroe would have been better role models for her.
I agree. She just wasn’t THAT good. She could get most of the song, but, when she clunked, SHE CLUNKED. Didn’t she put out a CD afterwards?
