You're not getting the direct filmgoer experience of that culture, just the best fruits, and that's perfectly fine because if you like their best you may find more in their second-best that you will also absolutely enjoy, just like in Westernized media.
Just like books, I guess. :)
This is really not true from what I can see. European films are routinely subtitled for other languages. (They used to be dubbed instead).
And even cheap and cheerful Bollywood and Chinese movies find a distributor and a bad translation.
Perhaps this is more of a problem on US streaming services. You do have to want to find these things, to some extent. But almost all cinema is produced with a global audience in mind.
Like all the Taken movies, or A Boy And His Dog, or anything Steven Seagal made after he discovered Russian money.
"Challenging" is such a bullshit term. It implies there's something meaty for your brain to chew on, but 9/10 times it's a pretentious way to write off people who don't like hamfisted righteousness that fits squarely into run-of-the-mill positions and ideas that are Hollywood-safe.
Those movies are pablum just as much as marvel franchises or 90 minutes of fart and dick jokes.
