Fans who use the terms "sexism" and "diversity" (among a few other similar terms) to push their own agendas, rather than making an unbiased judgement call on the actual work. Push your politics somewhere else and employ some critical thinking using actual logic and reason, not your over-caffeinated emotions.
Fans who use the term "iconic" as only a way to defend a negative opinion about a current title. No, that old....whatever....is not "iconic" its just old. Very few things are actually "iconic". In comics, I'd say that there are five truly iconic characters; Superman, Wonder Woman, Batman, Robin, and Spider-Man. Others might come close (Flash, Captain America) or currently be enjoying a spike in popularity (Iron Man). That does not make them iconic.
Writers who say their next story is going to "shake the hero to his/her very core!" or are "getting back to basics" or are doing "the biggest game changer ever and nothing will ever be the same!" or are "going to find the hero's humanity". Those statements are almost certainly going to ensure I stop reading.
Hal Jordan is a terribly boring character who has had the good fortune to be in lots of good stories.
Nathan Fillian could probably change my mind about Hal Jordan.
Deadpool is not funny.
