My family has been completely transfixed by the BBC series Planet Earth . Five years in the making, this spectacular 11-part documentary goes far beyond any nature programs in history. Photography is breathtaking. Information is fascinating. You will want to own it (though it is also available at Netflix) because it is worth watching again and again. We do not have a HD DVD player, but even on a standard player the photography is absolutely eye-popping. It isn’t excessively preachy. Global warming is mentioned only once or twice. The message is more implicit — who would want to tamper with this glorious creation?
