I am not talking about anyone specifically but some fans are under the delusion that if things are not done their way it is going to die. A good ship has room for everyone but sometimes people think that being on the ship makes them the captain. They think that when they get off the ship it is not going to run.
I have seen some fans talk about their dislike Guardians of Galaxy series or The Thor Ragnarok movie. The thing is those movies have successful cultivated a new base with new direction. Sometimes new direction what a franchise need in spite of the long time fans not liking it. Just given how active DC was the property I can safely assume that financially it was not setting the world on fire which general means the future of franchise depends on being able to attract new readers and fans more than it does maintaining old fans.. That doesn't mean you alienate or ignore the older fans but you can't let old fan stop you from modernizing your franchise for future success.
