This is truely top class tv show and I really love it. I do not watch many tv shows under the Documentary category, but this was great and now I am bigger fan of tv shows of this kind. If a tv show can keep me focused for the full tv show time, that's really great. Anyway, this genre may boast of one of the larger number of titles. I've been a big fan of such cinema for some time. It's a tv show for everyone, I'm sure you'll like it after watching.
