It wasn't Asimov I meant, but he's a good example (and didn't he say it himself during his life?) He wrote characters straight from the writers' stock trunk, there to prop up some interesting science. Lady Friend is more patient with that, but Gay Panda wants to look at the science or magical elements through the eyes of someone to whom I can relate, not a cipher. It's just a personal preference.
One of my favorite shows growing up was Star Trek: The Next Generation. I loved the gadgets but what brought me back every week were the people. I couldn't get into DS9 because I found the characters flatter, and that got in the way of enjoying the science.
