Why bother going to the Arctic at all? Why not do it all with CGI?
As far as I can tell, this is just trollbait to get that certain subset of the population who go "editing! music! it's not PURE!" whenever they see wildlife telly.
All the trickery doesn't bother me in the slightest and I don't notice the music.One thing, though, that I would like to see would be the Northern Nights in real time. Every time (and I mean every time) they show them they're speeded up.
