Some people get labeled "haters" and "sticks in the mud" because that's the way they behave, not because of what they like.
In fact, the way they're treated has nothing to do with what they like. It's a response to the amount of energy they expend and attention they try to command for their repetitious complaints about everything they don't like - which is generally anything that isn't already familiar to them. The basic position is that any change to a bit of entertainment in which they're emotionally invested is a personal insult, disrespectful of them as people and deeply hurtful.
They just repeat those complaints over, and over and over, seemingly always alert for a new potential assault on their sensibilities as a fresh opportunity to take loud and personal offense.
There are only a couple of posters I can think of on this board who strongly dislike Star Trek TOS or the last forty years of Superman comics and the like. In fact, most the people on this board who are most enthusiastic about Abrams's Star Trek movie really like the original Star Trek - which simply makes sense, if you give it a moment's thought. Likewise just about everyone getting excited by what they see of the new Superman movie adore the character and his history; many have read those comics faithfully for decades.
On the other hand, the most persistent and vocal objectors to new versions of stuff speak of it and often of the people who like it in the most dismissive and arrogant ways. "Ruined," "trash," "aimed at impatient kids with the attention spans of moths" are some of the creative ways in which they express their unwillingness to let other people enjoy what they don't. They start topics bemoaning the "desecration of popular culture icons" and wondering rhetorically what's wrong with the world that it's so determined to change "for the sake of change" when that makes them so unhappy and uncomfortable.
And they do it at the very first sign on the horizon of something new that they don't like - the first bit of news the first image associated with a new project which suggests that they might not be getting exactly what's already familiar to them.. The language and reasoning which they employ to express the unacceptability of change almost define the notion of "contempt prior to investigation."
And when they're called on it then suddenly it's "six of one, half dozen of the other," "live and let live," "different strokes" and so on. No one is fooled. You have on the one hand a lot of people who are pleased and excited when they get news about upcoming movies and tv shows...and you have another group who react to anything new and unfamiliar as an unbearable attack on their personal values and world view. To pretend that when you compare extreme examples of the two positions you find some kind of symmetry is a joke.
