Nope, including the LotR movies. I will die on this hill.
Specifically, Robert Zemeckis > Peter Jackson. the BttF trilogy was masterfully executed with great plot, pacing, and incredible attention to detail (down to things like e.g. "Twin Pines Mall" becoming "Lone Pine Mall" because Marty ran over one of Old Man Peabody's pines). Meanwhile, Peter Jackson couldn't even figure out how to get major plot points like the Scouring of the Shire to work, let alone Tom Bombadil.
No, you misunderstood. "Not even X, let alone Y" is just as much about differences in magnitude as it is similarities in kind:
Meanwhile, Peter Jackson couldn't even figure out how to get major plot points like the Scouring of the Shire to work, let alone [minor ones like] Tom Bombadil.
be that as it may, even “Scouring…” would have been a bad choice to include in RoTK. The ending is already way too long. I would have loved it as fan service, but from the perspective of film making cutting it was the right choice.
Together, we will defend this hill until we slay every last orc, mage, rohirrim, man, elf, big footed people, walking trees (are they triffids?), beast of hell, dragons and what have you.
WE ARE DARTH VADER, FROM THE PLANET VULCAN. WE ARE ARMED WITH WALKMANS FULLY LOADED WITH SOLID VANHALEN SLUGS.
And we have a full case of stolen plutonium by our side. It shouldn't be that hard.
