Actually Gophie....I think I'm undecided on that one. The Planet Earth is more a feast for your eyes. It IS however, a little lacking in identifying what you are looking at. (unlike National Geographic which includes an education in what you are looking at)
One thing I noticed watching the Planet Earth, (there were 6 of us watching) that between the OOO's and AHHH's, were a lot of..."what IS that"......"what is THAT"........"WHAT is THAT"....... Lots of rewinding to see if we had missed something. But we hadn't.
