I don't think the wired thing makes any sense. Movies which go against the formula have garnered more success like Thor Ragnarok, GOTG, CA:WS, etc. and movies which are 'bland' and generic like AMATW have failed. Ofcourse there are outliers like Captain Marvel but they can piggyback the success of consistently successful movies coming after them and before them. That is unfortunately not possible with DC movies due to the inconsistency in quality of the movies.BvS has garnered a pretty big following since, mostly based on the extended cut which restores Snyder's vision. I think you're right about how people are wired, though, I could picture them even rejecting a new Nolan Batman film.
