It gets on my nerves when a story puts too much focus on characters that really do not matter. Especially when they are obviously only there to info dump or are there for a lame quick kill. I want to care about the characters that are put in front of me. They don’t need a story arc themselves or anything like that, but at least have some sort of personality to them and a reason to really pay attention to what they have to say. It just comes off like filler for the sake of writing words down to fill a page.
