Earthlight Special Edition is special and I'm glad I've bought it. In parts it is awe inspiring stuff: sand dunes draped over desert rock, land locked seas with swirling sediment washed in from rushing rivers - and all in high resolution. This is the stuff for geologists to die for. The disappointing parts for me were something I should have thought through: 70% of the Earth is ocean; about 70% of the footage is over the oceans. The cloud tops ARE fascinating but the overland footage is spectacular and offers so much more to see and wonder at. This is a great DVD and you should get it, but much as I'd like to fly a mission with the NASA team, they need to teach the crews a bit more finesse with the camera technique. This title promises so much, but for me, it didn't quite deliver. 7/10.
