Here's a wonderful article that explains
character agency. A majority of stories that suck have a problem with absent agency; the characters get railroaded. This is not fun.
I on the other hand like characters who can get into trouble on their own, and audiences who can suggest exciting trouble into which characters can get. Nothing is more entertaining than having someone say, "Hey, there's a six-foot-wide mud puddle over there," and the main character goes, "Nah, I'd rather burn down the barn instead." Or whatever.
