BBC has just started broadcasting its new natural world series, called Frozen Planet, narrated by no other by David Attenborough. So far, the first episode is out.
I've watched the first episode in 1080i and it is absolutely mind blowingly stunning!
If you thought "Planet Earth" and "Life" looked great, wait till you see this. I am not kidding. It is THAT good!
See if you can find a high-def torrent. It is definitely worth downloading until bluray comes out sometime next year.
