Her characterization was so light in TFA I’m not even sure a novel could flesh her out enough for me to find her interesting.
You’re telling me you’ve never found a character in a novel interesting.
That’s not what I’m saying; what I’m saying is that she has so little characterization that not even a novel could add a significant amount depth to her.
That doesn’t make any sense. If she had little to no characterization, a novel would have plenty of space to add depth.
Think of all the characters who don’t even exist before they appear in a novel. You’re saying not even a novel could add depth to them?
