Having done the George Lucas approved chronological, special edition marathon myself, I can safely say it does not work. The break between episodes III and IV is simply too jarring. You could also try and cut some out of the rotation because you think they suck, but you’ll inevitably miss large pieces of the story that way.

I think it’s important to recognize that Star Wars is the beginning, the opening shot, the 20-30 mins or so of exposition before anything even happens, the fact that it was originally made to be seen as a singular movie. And from there on realize that Episode I throws you right into the action and assumes you know exactly what a jedi, the force, a droid, and who Obi-Wan is and simply doesn’t work as an introduction to the universe. And from there on further realize that Episode III is the ending that brings everything full circle.

Realize on top of all this that they are indeed separate trilogies, made separately and telling two different stories. So you cannot really mix them up and get anything coherent either.

Only one order emerges from this: Release order. This is how they were made to be seen, each movie assuming only that you know what came before.

TFA doesn’t really fit in anywhere. It’s its own thing.
