The problem for US cinema is that US filmgoers hate watching films with subtitles, and their dubbing industry is unable to cope with films from elsewhere in the world. They only watch a tiny fraction of the films available from outside the USA.

By contrast, other countries either have an excellent dubbing industry (like, say, Germany) or are accustomed to watching with subtitles (e.g. the Netherlands).

Hollywood films have so much money and industry-style capacity behind them that in a really free market they'd just swamp the world with wall-to-wall crap and kill off other film industries. They've effectively locked out most foreign films in the USA, but that's no reason why other countries should emulate them. The French still make some pretty decent films, as do the Germans, but while the French and Germans get to see those films (and other European films) in addition to US stuff, the Yanks don't get to see European films. Their loss!
