If we're talking original intent, what you saw for SF in 1979 is the original intent. The Wise of 2000 who approved the DE was 20 years older
Well said! And if we wait another 20 years, the "original intent" would probably change even more.
I'm sure thousands of artists practice this kind of revisionism. Ask any one of them, and they ALL have ideas on how to improve their different works, or that the "original intent" hasn't been met a 100 %. Does that mean they should all tinker with their works some 20+ years later?
Whether they should or not is something of a case-by-case basis.
As long as the unaltered work is also preserved, then another version with revisions is fine.
The theatrical version of TMP is still there.
However, Robert Wise was never satisfied with the movie in it's theatrical form. This is simply fact.
I have great love for both versions, and a little retroactive fan-wankiness, if it actually fits the film and it's universe, is fine with me.
If they produce a HD version of the DE, I believe the team responsible should not stray far from the DE as presented on DVD.
Perhaps very slight, subtle tweaks and upgrades to the new VFX shots, and cleaning up of compositing issues in a few places (the beginning shots of the Klingon ships being patterned by V'ger for example).
I personally like the Blade Runner Final Cut approach, where the original is restored and cleaned up, and distributed in disc along with the restored DE.
