Basically, if it doesn't make a heap of money for Hollywood executives and investors, then it's not really culture, right?
That's a rhetorical way to put things. I can take your phrase verbatim and make it look as bad or worse for politically-backed productions by just changing the target:
"Basically, if it doesn't give a lot of power to politicians and the lobbies that support them, then it's not really culture, right?"
Everyone, no matter their background, flocks to the cinema for their entertainment. They all listen to music for which they have paid - music approved by RIAA represented companies.
It's their choice. Don't act like the Internet doesn't exist, you can obtain almost anything you want, it's all one or two clicks away. Take it, show others, cause them to notice there's better stuff out there, just don't impose any of it on them. Let them decide.
"Action thriller" is just about synonymous with "brain dead".
And that's bad because...? If people like to have some escapist fun, what's the problem? Aren't they entitled to their small doses of endorphin? People want fun, let them have fun. It isn't like they cannot pursue higher goals at other times. Nudge them in that direction if you feel you must, but in the end always, always let they chose for themselves. As long as they aren't imposing their preferences upon you, it's their prerogative and it should be respected.
