I think there’s probably a middle ground between that and what the film gave us, where you’re still dropping into the battle with some build up (but not making it a whole sequence).
I don’t know, the primary problem with the Mustafar sequence isn’t so much how frenetic it is, it’s the geography. There’s no shot that shows where you are and where he’s going. Whether that shot comes after he’s bodyslammed someone, or before he starts his rampage - the biggest problem with the sequence is that missing shot showing you where he is and what direction he’s trying to go. Abrams & Co. just cut into the bone trying to save this sequence and I think they fundamentally broke it in the process.
If I had any other film to compare it to, I’d say it’s sort of like how the open of Alien 3 became a disconnected montage that also fundamentally breaks itself as it goes. This is probably worse than that, in that almost none of the Mustafar information being imparted is as necessary as Alien 3’s opening is to its movie.
