ELI5: It seems like WWII is more prevalent in pop culture than WWI. For example, why are there way more movies about WWII than WWI?

For one thing, Hollywood is an American industry that likes to make movies about American characters.  Since American troops only arrived in the final year of the war, there isn't much time for a story.

For another thing, the Western Front was pretty much stagnant for most of the war.  "We're in our trench and they're in their trench, and we're both getting blown to bits by artillery" doesn't make for a very compelling action movie.  The Eastern and other fronts were much more active, but again, a movie about Russians fighting Germans is a hard sell to Hollywood executives.

Finally, WWI didn't have a Hollywood "win".  Audiences want a happy ending, and "we decided to stop fighting, and Germany conceded some territory" isn't very satisfying.  The complicated politics that led up to the war also makes it more difficult to paint the Germans as villains.  With WWII it's much simpler: "Nazis = evil" is the easiest villain story there is.
