Just received a rejection from a big deal journal, and the guy writing to me went out of his way to praise my concept before he explained that the story meandered too much. It's a fair cop. He even asked me to send again, which was unexpected. But then he added that he really liked it when my characters cooperated at the end for a righteous purpose.
I was weirded out by his interpretation of my characters' actions. Because they didn't have a righteous purpose at all. They were trying to kill a guy.
