Let me answer with a counter question

: is that group of people actually interested in that type of movies?
Meaning: if there is no demand, there will be no supply. And in the movie business there rarely is a supply before there is a demand. People want to see certain types of movies, and in this case, the majority wins and the minority (that group in this case) loses.
That small group may want to have different kinds of movies, but when they complain, and then don't show up when a movie IS in their league, what is the use of even making them? So.. as far as if they should make more of those movies.. unless there is an audience, a SHOW-UP audience, my opinion is no.
