TLJ, as someone mentioned, has far higher highs and for me, it's frustrating how it can't quite get the rest of the movie across the finish line. i feel like one more script revision would have really gone a long way. It's frustrating to me just how close TLJ is to greatness.
On the ROTS side, we had Lucas actually try rewriting scenes after principle photography without re-shooting. The Anakin turn sequence is famous for this. (i'm sort of curious to see what that scene looked like before it was reconstructed. The Senate clearly ends up with Anakin's saber at some point during his fight with Mace. )
