Query: Ghastly

I don't know why the Discovery Channel insist on buying BBC programmes then -- after massively dumbing down the script -- getting someone who hasn't the first clue on the subject to narrate. They made the same mistake with Planet Earth and replacing Attenborough with Sigourney Weaver.Attenborough has been doing nature shows for the BBC since the 1950s and has had a passion for natural sciences since he was a child. Oprah is a talk show host.Don't buy this knock-off, get the Attenborough version and get narration from someone who's been in the business since the start.
