That’s ridiculous. No one’s watching these movies for the plot. If you skip ANH, you’re skipping the whole point.
Not to mention, you are missing a vital chapter in the story of the main characters (though I guess that’s beside your point).
Now, skipping ROTJ on the other hand… an interesting idea.
I’m increasingly of the opinion that these reworked viewing orders are more trouble than they’re worth. There was an argument for it in the days before the ST when a release-order viewing was a bummer because it ended with the PT, but now that there’s another act, I think there’s less reason to break up trilogies. And if we really want to get heretical, I think it would probably be fine for someone with no SW experience who wants to get in on the fun of TROS to skip right to the ST if they’re pressed for time; TFA is pretty much designed to be a secondary entry point.
I would agree with this, though only if the person in question already knows the Empire twist. That’s too good a moment to miss.
