I Love Everyone.
Best blog post ever.

Do you have you have to love all your characters? Probably not, might be good to hate some of them. I do think it's important to find them all interesting though, and to feel passionate about them. If a character in something I'm writing doesn't interest me or make me feel strongly I often find those are the ones that should be revised and can easily be cut.
In an early draft of What the Water Gave Us I cut out three fairly good sized secondary characters, one of whom was playing a very important villain role. I found that they all served a purpose in the plot, but that was mostly it, they were one dimensional, and it was easy to pick them out because I didn't love them, (or hate them) I didn't feel much of anything for them. I cut them out and reassigned any important plot functions to other stronger more passionate characters and the story is stronger without them.
So if you find yourself not loving everyone maybe take a look and see if some characters need to be cut out.
