The point is more people watch the shows than nerds like us. If they only appeal to the stuff we think is interesting they will fail in epic fashion.And that is my exact problem with expanded universes and how they are handled. These are not comics. These are movie series that are getting turned into multimedia projects that end up chocking the life out of them. It's classic, boring, unartistic capitalism.
Using your analogy, I think it's unfair to blame fans if they are taught that that's how it works. Take Bryan Danielson. WWE didn't want to strap him up 2014. But they did. Why? Because those who worked themselves into a shoot got what they wanted. It's fine to say, "don't believe the rumors". But Marvel built an entire 2 billion dollar movie around believing a rumor.
As for your last sentence, what is your point?
Is your argument that I should care if it appeals to the masses? Why? I like the Penguin. I think it's good. I think it could be better, with better writing. That's basic critique. We all do it.The point is more people watch the shows than nerds like us. If they only appeal to the stuff we think is interesting they will fail in epic fashion.
Rumors are fine, they are fun and they give us something to talk about. When people care more about their head canon based on those rumors than the stories being told then they are the problem not the studios.
I am not saying "dont believe the rumors" what I am saying is "just because there is rumors doesn't mean those were real or that they were in any way better than what we got". I had enough of that with the people who thought the Tim Burton Superman was going to be amazing...
