If you're looking for some great HD eye candy, check out Planet Earth on the Discovery Channel. I watched it last night, great photography. Not much in depth about the places and things they covered, but the scenery was awesome.

Agreed on the lack of the depth. They globe trotted around and spent just enough time in each area for some cool landscape visuals or for "never filmed before" events. I did appreciate, while watching it with my first grader, that they skipped "the kill" in the hunting scenes (at least in the parts I saw). Overall, it was cool.

Not as cool as the 1980's documentary of the same name, however. That one wasn't as pretty, but good nerd candy.
