Well what there was was great,
1st episode an overview of amphibians and reptiles, amazing turtles frozen only to thaw in spring, I was amazed!
2nd one amphibians, frogs have been done to death but some interesting stuff on salamanders.
3rd one on lizards, wow the tiniest chameleon in the world and it is a small as a beatle!
4th one is on snakes, I thought this one would be kind of boring but it turned out to be the most interesting one.
5th one on turtles and crocs, this one should have been two, turtle and tortoises and sea turtles can fill an episode for sure (sea turtles have been done to death as well) and crocs and alligators can fill an episode.
David Attenborough is a behaviorist so I guess that's why he gives birds and mammals and even fish so much attention, but I find turtles and tortoises to be some of the most amazing animals on the planet.
What there is is excellent, i just wish there was more.
