Having watched all of both series, I felt like the 2nd series had more ‘young animals getting away’ and also more sound effects with some of the smaller things. At times it was actually a bit distracting. A mouse running through some brush for instance had all these practically human sounds… I also had a similar feeling when watching the editing and humanization that took place for different interactions. It can feel contrived at times. I suppose that is what all of reality TV is doing. As long as it doesn’t ultimately misrepresent the info - and BBC is pretty good at not doing that - then I think it’s all pretty passable.
