Query: Video is amazing, but is by far awful due to Oprah.

This is a great series, just like Planet Earth was. Shots are amazing and beautifully done but Oprah just ruins it! She shouldn't be in this. This is the American version which i'm sure lost BBC a lot of money. Go and buy the regular version with David as the Narrator. It is extremely better. You might have to order on line but is so much better
