I'm sorry if I've been unfair. As I've said, I certainly don't think it's true to say that the majority of people can't or won't use their imaginations, and I do think most readers/viewers like a mix of dimensionality in their characters.

I also think, however, that some of those who loudly complain about characters being "one-dimensional" or "cardboard" simply don't choose to put in the effort of engaging with a story or a character. They almost certainly have imagination and could engage if they wanted to, but they prefer to stay detached and criticise from that viewpoint because it makes them seem clever. To themselves at least. And that I have no patience with.
