I may be slightly biased towards Earth being that its the only planet I have ever been on, but I must highly recommend the above documentary. This is not the Discovery Channel edition however. David Attenbourgh is the narrator not Sigourney Weaver. He has way more street cred being that he has been the voice of British naturalist documentaries for 50+ years and he is a Sir. He was NOT in Alien. I would imagine he would also not look as charming running around on a spaceship either. So anyway this offers an exciting new look at our planet's different environments and wildlife. The documentary was filmed over 5 years at over 200 locations and had a budget of $25 million.
