The lack of DE versions is why I have yet to re-buy the TOS movies on blu ray yet.
I'm much happier with the theatrical cuts. Never was much of a "DE" man. Usually scenes are cut for a good reason.
In the case of TMP, it's kind of baffling that they'd cut out something like this.
The theatrical release may be the theatrical release, but in the end the DE is a needed polish the film should have gotten in the first place. Kind of like how the 1998 cut of TOUCH OF EVIL should have been the theatrical release, it just works better, no matter if it was the theatrical cut or not. In the end, like that film, I'd like to see all versions available in one package rather than separated as TMP currently is. At least give viewers a choice.
