I love me some Animal Planet and a good runner up is definitely any show that might be found on Animal Planet. Netflix currently has a slew of fab Martin Clunes animal shows and I binged on them all! A more endearing and charming host you could not find. Clunes has a delightful sense of wonder that's utterly infectious. I absolutely adore this man. If you find several hours of free time, get thee to Netflix and watch Mr. Clunes in all the documentaies they've got. You'll love every damn minute, I promise you.
(look at that face! doesn't he just make you smile instantly?)
