What things about comic books annoys you? Here's what annoys me a bit about comics:
1. Lack of character development in some comics - If a certain storyline in a comic book doesn't develop the characters for whatever huge event comes by, then I would easily get annoyed by it since I want to see how the characters have to struggle up until that particular event (AvX is a really good example of this)
2. Drastically changing characters' personalities - along with not having any character development, if the characters' personalities drastically change and there is no previous story to back it up, then I could easily get turned off by the character or the event at hand because they didn't developed the situation.
