I've borrowed this on DVD from the library a few times... he's a fantastic narrator really!
I watched it with my aunt one time, didn't tell her who was narrating it and she told me that the narrator was very good, very clear in his pronounciation, was easy to listen to and understand and that he had a fantastic voice all together...
My aunt is a retired English teacher and she usually never have anyhing nice to say about narrators on the telly...
And I have to agree! I love TV shows like that, and Ben really does a fantastic job
