Thanks, Benny! What you’re noticing about overplayed emotion in some literary writing is usually called “sentimentalism,” and it’s something good writers try to avoid.
It’s hard, of course! There’s a balance to strike that often isn’t easy to get right.
You want to build a genuine character your readers care about and then offer genuine emotion from a reastic point of view.
Creative writing teachers will often use the example of “writing a cute kitten and then killing it just to make your readers cry” to point out a blatant instance of sentimentalism.
Problems with sentimental writing are often more subtle than that, sadly. If only it were so easy. ;-)
I appreciate your comment!
