I thought The Last Samurai was mostly forgettable but I recently watched the Shogun remake and have to admit I was impressed. Stunningly gorgeous cinematography and masterful acting by everyone in the cast. They took pains to reduce the Eurocentricism from the source material, but the protagonist is still a white dude so there is some lingering White Saviorness to it. But he’s mostly portrayed as a lovable buffoon and witness to the historical events unfolding around him rather than its impetus. Sanada and Sawai are the real stars here.
The US is probably the outlier here with too few regional accents given the vast land mass. I would attribute it to the population growing alongside the successive innovations of rail, radio and television so that regional dialects blended into each other.
