Here's an annoying one for me.

Working on my own WIP- an Urban fantasy, I believe, would be the correct category- and I've run into an issue with Character favoritism. For instance, I can write all day & give myself no qualms about rewriting & devoting time to "getting things right" for my three main characters- Juu, Tim & Merissa. However, when I switch over to, say, the main antagonist, or a quick scene from the POV of Tim's uncle, I get bored & am just plain uninterested. The problem being that this novel is going to have, at least, another six side characters & half of them will also have POV scenes...

Anyone else have this problem? How'd you overcome it?
