I "only" watched it in HD. It's fairly low on "nature red in tooth and claw" which is quite welcome and very high on sheer wonder. Some of the colourscapes (that's the best word I can come up with) are simply amazing. You are often put within a few inches of fast moving fish, dolphins etc and can see muscles, scales, pincers, arms, fins all moving perfectly clearly. I have no idea how the heck they get cameras to work in amongst coral and hollows in rocks and follow swift action. If my TV license fee goes towards turning out this sort of thing sometimes then I'm a very happy bunny.
