if i were going to rank all 8 movies (from worst to best), i would put them as follows:
Ep 1- Phantom Menace
Ep 2- Attack of the Clones
Ep 7- Force Awakens
Ep 3- Revenge of the Sith
Ep 4- New Hope
Rogue One
Ep 5- Empire Strikes Back
Ep 6- Return of the Jedi
now, this order is DRASTICALLY different than it would have been a few years ago. When they released the 6 pack on Blu-Ray all together, i made myself a Star Wars weekend. Up until that point, Ep 1 was the worst, but Ep 6 was one that i never really cared for. Upon the rewatch, i found that i REALLY liked that one. i couldn't believe it, as i always had Empire as the top.
Also, i want to point out that i really did like both Episodes 2 and 3, so Force Awakens falling in between them is not a knock on it. The only SW movie i legitimately have no love for is Phantom Menace. Well, and the Holiday Special, but for obvious reasons i'm not counting that. (although if an official bluray ever comes out, i will buy it day one).
