Query: Simply stunning, a must own for HD owners

These videos are amazing and a must own for HD/orBlueray owners to show off to your friends, because the visuals will blow you/them away! I loved it and the guy narrating it is way better than Sigorney was, in my opinion anyway. I am still stunned about how clear it is and detailed almost every scene is. This is a must own for any HDTV owner.Now yes, I would have liked some extra bonus footage, but do you really want to take back the BlueRay HD for the regular DVD for that reason only? If you do you're crazy because the pictures in HD are 100 times better than you will see on standard DVD. This series needs to be owned by every HD owner, and nature lover for that matter (though Im no tree hugger I do appreciate this glorious work of art we call earth). Purchase this with no hesitation.
