For all of the flaws I see in the movie now, TWOK is still my favorite. Do a slo-mo sometime on just the starship fight scenes - they are some of the most information dense scenes of any Star Trek movie. There are so many split-second shots, you can't keep track of them.
Now if they could just make a special edition/director's cut with redone outer space FX. The CGI is so good now that they could go back and redo all of the scenes with the Enterprise & Reliant and clean them up. And get rid of the reused footage from TMP.
