I watched the first episode of Journey to the Centre of the Planet last night and I did not expect what I got. The science advisers, visual designers, writers, editors, animators, and everyone else involved made an excellent first episode. In fact, if the series continues to be as good as this first episode, I think I would end up considering it the second best science series I've seen after Sagan's early 80's astrophysics series Cosmos. (That remains to be seen.)
Hammond is having an amazing year. His recent season of Engineering Connections was very, very good. I thought it was his best non-Top Gear work until I saw this first installment of Journey to the Centre of the Plane.
(edited because I typed Earth instead of Planet in the show's title. It must be that the British (mis)spelling of center as "centre" addled my thoughts.)
