The OG trilogy? No way. Maybe the third one a bit with all the ewoks. By then it was already a hit and I guess they knew kids enjoyed it.Perhaps if you’re using a rather young age as a cutoff for the term “children”. But older children absolutely lap it up, same as they do with video games that require the use of skill and memory.
Obviously someone who is just past toddler-hood will not dive into this stuff the same as a 10-year old, but that doesn’t mean it’s not designed at least partially with children in mind.
But it's just not a kids film. In the first film for example;
Luke's family are killed (off screen)
Leighs planet is blown up.
Loads of Xwings pilots are killed.
I know it's a different generation but compare it to the likes of Pirates of the Carribbean or whatever.
