Well, there is a major plot twist in episode 5, The Empire Strikes Back, that will not be a surprise to you if you watch the prequels first. Whereas if you watch 4, 5 and 6 first, this plot twist will be a surprise to you. It involves Darth Vader and I'm assuming you don't know about it so I won't say anything about it so as not to ruin it for you.
I think maybe it would be more fun for you to watch 4, 5 and 6 first, not only because that's how they were originally released, but also to keep this plot development a surprise you before you watch the prequels.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
