Who rattled your cage? The notion that her career has failed to deliver simply because she hasn't won enough awards is ridiculous. Hollywood hype is marketing, to expect career full of awards based on that hype is nothing short of naive.
Nobody rattled my cage.
Just pointing out that it's obvious - from a purely artistic/critical perspective (which is what is being discussed) - she could have chosen far more worthy/challenging roles if she'd wanted to. I don't doubt plenty would have been offered to her.
So in that sense, it's actually quite reasonable to say she hasn't delivered on her potential. All depends how you look at it.
