What exactly makes a character a strong character? Are we referring to a strong will or physical strength, or is a “strong” character just another way of saying “good” character?
I tend to use it as a synonym for “good” or “well-written”. A strong character to me is one that is written well enough that they feel like a fully-fleshed out individual whose personality is not based on shorthand, stereotype or contrivance. Basically it’s a character who is written like they were an actual human being rather than a fictional character
