I should point out that Star Wars won an Academy Award for editing (due in no small part to the work of Marcia Lucas), so being in awe of its original editing is not unwarranted.
People tend not to realize I suppose that Lucas oversaw the editing team and even did some editing himself on the film.
This. The editors said it themselves when receiving the Academy Award.

This seems a good place to put this but I’m assuming many here have already seen it.
