After rejecting it for a while, I honestly think an 3 hour epic cut of both films could be cool. I will still just be sticking to doing a regular last jedi edit but am looking forward to the 2 in 1’s that will be done.
They have such different visual aesthetics, and I don’t know if that would take me out of the whole experience.
Maybe after changing the colour palette of the movie slighty to be a bit more similar to each other, it might make it seem more natural but being an edit of 2 different films (3 depending on how ep9 is) it will always seem a bit out of place but not drastically.
