Or every ethnic group isn't entitled to their own set of TV shows, movies, etc especially if there isn't enough demand to justify it.
I think your way of thinking ties too closely with the failed multiculturalism experiments of the 20th century. Trying to artificially make media fit for various demographics leads to low quality media, tax increases, and ultimately a certain level of isolation.
In the USA in the 70s and 80s, we tried this sort of thing. There was a cola for black people, urban newspapers for the black community, we encouraged them to go to traditionally black colleges, we encouraged them entering traditionally black jobs, staying in traditionally black communities, staying out of the suburbs, etc. Instead of trying to integrate them into the mainstream, we isolated them. It was a disservice. The same thing is happening all over the world, especially with Muslims immigrants. We can see the multicultural mindset causing problems in Europe, especially in the UK and France.
Even if we took your argument on face value, what then? Some kind of quota for Irish directors? So we turn down an English director with great ideas and lots of talent for some Irish director because you feel, as an Irish person, that somehow you can feel his "Irishness" via his directorial decisions? So if he made a sci-fi film about the future on another planet, you'll absorb some level of Irishness from this? That's absurd.
I think its time we put multiculturism down and accept that a certain level of assimilation is normal and healthy. If your entire cultural identity is at risk from a Michael Bay film, well, that sounds like it wasn't too strong to begin with. My parents were immigrants. I feel only a superficial connection to their culture. I don't see why that's so terrible. Their great grandparents came from another culture as well. The idea that we need to protect those from a certain culture from change is highly questionable.
