ELI5: Why are there a lot of WW2 movies and almost no movies about WW1?
gpt
There was widespread opinion after WW1 that it shouldn't have happened, and accomplished nothing.  Its causes are still a bit hard to understand, and it discredited pretty much every government involved in it to one level or another.

And while it was happening, the horror was ironically uneventful.  People died in droves, but not much changed - the front lines did not advance much for most of the war.  People might unknowingly clamber over multiple layers of buried corpses trying to capture the same few meters year after year.

World War 2 was very different.  It was one of the few wars in history that can be legitimately called *totally* unavoidable, given the mentality on one side.  Its causes were clear, its moral distinctions eventually were found to be absolute, and its events and movements were very dramatic.

Its outcome was also economically and politically profitable to the country that houses Hollywood, so lots of movies about it were inevitable.
