Susan Boyle isn't trying to become a Celine Dion or Barbara Streisand. She simply went on "Britain's Got Talent" to just try and do something that her dead mom suggested.
She's not trying to take over the world or being something she's not.
Do not make her over. Let her be her. And yes she does have talent, and yes there are plenty of people more talented than her. So what. Let her have her 15 minutes and shut the fuck.
She's quite funny and goofy. Just go with the flow, enjoy.
Ah, I know I feel better now.
