givesmevoice, I think you and I are probably the only two people who agree on O'Hara being quite bland. I don't really dislike her, I just find her incredibly uninteresting as a performer though I definitely respect her fans and I can see why people like her.
Still, I can't imagine her knocking this out of the park in the way that Katie Finneran would, she's simply brilliant and this is the role for her.
