The Harry Potter star admits she is appalled by TV show producers who aim for big ratings by featuring contestants at their lowest points.
She tells Britain's Radio Times, ""There's not enough drama being made. We've got too many reality shows, but that's probably just a fashion so I'm waiting for things to swing back.
""I also get very angry that vulnerable people appear in the audition stages of TV talent shows. I think it's sad that people's real vulnerabilities are being exploited. They simply shouldn't be there.""
