Another example is Titans of Space. I really enjoyed this (especially as I'm a planetary astrophysicist by training) but I think I was missing out on the scale of things. This was most obvious to me in the 'scale shrinking' parts. I think it says something like 'we're shrinking space now so X should be about the size of a beachball' or something and I didn't really notice any change before the 'shrinking' and after. It looked about the same to me.
