Are you sure you got the argument I'm presenting? You did quickly make an edit to avoid a rather rude remark.
My point is that their use of literary devices, as you put it, are often misleading if not flat out wrong. The listener needs to he able identify them as such, and I don't think that's a good way to communicate science.
It doesn't mean that PBS is bad. Note that I have made no such statement. I'm just saying that I dislike it, and tried to be constructive as to why. If this offended you, like your initial remark might suggest, perhaps you are reading too much into it.
