Query: What were they thinking?

It is simply incomprehensible why The Discovery Channel felt they had to remove the excellent narration by David Attenborough and replace it with a dumbed-down script narrated cloyingly by, of all people, Oprah Winfrey. Do they think that their target audience is preschoolers?If you wonder why the US is falling behind other nations in certain academic fields, you have only to consider the thought process that led to creating this travesty. Shame, shame, shame, Discovery Channel.
