Having been brought up on BBC wildlife programs narrated by the incomparable Sir David Attenborough, I was curious to see if this American made program showed anything new and if it was any good, well there wasn't much that I haven't seen before, but the camera work was glorious and Tom Hanks have it a good go, although I do find his voice a bit irritating, over all the program probably would have been great, but found I the music and background sounds too invasive, could hardly hear the poor Tom and he wouldn't have been cheap. Anyway this was so distracting from the visuals I gave up with it.
