I Googled her. It brought up Disney's archives, which has this to say about Maleficent's decades-spanning quest to spread her wrath: "Beyond a matter of honor, this has become a matter of ego. Her pride, her evil, will not be denied." Insightful for a Disney synopsis, right? Just wait.
Here's what the site has to say about Ursula from The Little Mermaid: "She has the gross unsubtlety of Ratigan from 'The Great Mouse Detective' but substantially more brio."
Substantially more brio? I'm loving this site. More: "Bejewelled and lip-pouting like an overweight, over-rich, over-pampered, over-the-top society hostess gone mad, she is all flair, flamboyance and theatricality mixed with a touch of con-artistry. Except when her wrath -- the only genuine emotion she seems capable of expressing -- bursts through, her every movement is a deceitful artifice, as if she's performing for an audience." Read the rest here.
I would love to meet the clever, smartass intern who was assigned to make these up. But suffice to say: Disney doesn't make villains like these women anymore. Can you imagine a G-rated movie character employing the word "hell" these days?
