This having a 6.5 rating can ONLY be a political thing....this show is objectively EXCELLENT. If you love nature docs, you will love this...unless you can't get past the Obama thing I guess? No matter what you think about the man, Barrack Obama is very articulate and really has a great voice for this kind of thing. Now, to be clear, i watch nature documentaries for the scenery and the wonderful plants and animals. The voice is important to an extent, but I'm not focused on it. My score is based on the absolutely amazing footage! The lemurs jumping around in Madagascar was spectacular! Hippos in the Atlantic....penguins...crocodiles...all of it! Please do yourself a favor and either put your politics aside (watch it on mute if you must...it'll still be good) or ignore all the bad scores....this is really great stuff.
