The thing about Director's Editions is, where does it stop? Which version is the 'right' one? Does a theatrical cut trump a Director's Edition because it is what was originally theatrically distributed? Or does a Director's Edition trump a theatrical cut, because it is nominally "closer to a film-maker's original vision"? What about cases where scenes were cut out of the theatrical cut of something for a very good reason, and their inclusion in a subsequent Director's Edition actually arguably makes things
worse?
Sure, some Director's Cuts, including the TMP and TWOK ones, are broadly the same movie but just with alternative takes inserted here and there. They aren't 'canon busting' Director's Cuts. But then you've got DE's that have alternate endings and other major storyline changes, which confuse things somewhat. I've never been sure what's the official ending of Blade Runner. I've never been sure what's the true ending of Army Of Darkness. The Director's Cuts muddy the water to the extent that you can't necessarily say one way or the other which is the 'right' one, and to me that feels wrong somehow y'know?

I tend to err on the side of the theatrical cuts because I think for better or worse they
are the originals as released to the public and the Director's Editions can only ever be intriguing alternatives, but then you'll go online and many people will hold the opposite view, that the Director's Edition ending is somehow the more pure and untainted one.
(Actually, TWOK does make one major change: in one cut of the movie Peter Preston is seemingly just another eager young cadet, while in the Director's Cut he's identified as Scotty's nephew. A small change, but a significant one in canon terms. Which one is correct?

)
If they did a Director's Edition of "Generations" which reinstated Kirk being shot in the back instead of a bridge falling on him, which death becomes canon? If they did a Director's Edition of "Nemesis" with the original ending of Picard getting a new Number One, Crusher going off to Starfleet medical, etc, which obviously invalidates a great number of the original novels that have been written since (which all tend to use the theatrical edition ending as a jumping off point), then do we accept the Director's Edition as the new 'true' ending of the movie? Or do we just go "Hey, it's kind of cool to see it, but it
isn't canon"?
Sorry for the length of this one, but it's a topic which I've always struggled with.
