I dispute the contention that the Director's Cut of anything
is 'superior'. Certainly in the case of TWOK there's nothing IMO in the so-called 'Director's Edition' which puts it above the theatrical cut. Quite the reverse, I think the additions are entirely superfluous. I'm glad
the theatrical cut is the only one on Blu Ray.
All the Trek DC's are inferior to the theatrical releases, particularly TMP and TWOK.
In the age of the home video re-release, there seems to be a prevailing "oh, it's longer, it must be better" attitude. It's almost like collectors feel they're getting shortchanged in some way if they don't own every second of available footage. Pacing for the sake of the movie's best artistic intent is forgotten.
This isn't always the case of course, the extended version of The Abyss is significantly superior for instance. But I've found in general, extended versions at best add a few minutes of fluff, but more often than not, needlessly sour the final product to varying degrees.
