I'm a bit of a Space and Nature documentary junkie.
The BBC's 'Planet Earth', 'Life' and 'Human Planet' are simply phenomenal.
I also love the 'Wonders of the Solar System' and 'Wonders of the Universe' series with Brian Cox.
Give me anything with Space or Nature in general and I'm sold.
Watch Grizzly Man dude, you'll get nature and a weird person all rolled into one
The speaker sounds kinda silly but he makes some of the bestu documentaries out there!
And to anyone who dare, watch Baghdad ER, it's insanity :O
