I do think Original Trilogy-Prequels-Special Editions-TFA is probably the best way to go for a completist these days if you don’t want to skip a film or two and you don’t want to interrupt a trilogy, but also don’t want to jump straight from 3 to 7 or start with the prequels. It gives you the most complete overview of Star Wars possible, the good the bad and the ugly. If you’re new to it all you won’t “miss out” on getting the references to things like Jar Jar and “Han shot first” and you’ll understand the movies in more or less the same context the rest of us did. You’ll be able to easily form your own opinion on George’s “vision” and the direction Disney is taking it from there.

But for me I’d just go 4-5-3-6-7 if I was going to watch them now as I like the flashback effect of the 5-3-6 order and don’t believe either of the first two prequels is necessary for that, at least not when you’ve already seen them all before. Might not work as well for a first time viewer, not sure. But it’s the most satisfying dramatic experience for me from a storytelling perspective.
