After watching V2, I decided I prefer the Sanctuary as a middle arc over the Gunslinger. Which is a shame, because the Gunslinger obviously has more ties to Season 2. Sanctuary on the other hand adds so much emotional depth, despite being viewed as fillery.

The way V2 does handle Cara Dune however was really nice also since it gives her friendship with Mando more apparent history.

You have touched up on splitting the movies in 2, which could be worth it. One long 3 hour edit hybridding V1 & V2 would be a good idea too (like an extended edition). Or as you said, flashbacks can be implemented, but could be used in your EpII edit to give Fennec some background.

All in the all though, these edits are fantastic and I couldn’t think of how this couldn’t be down better!
