A gem of a movie that's often discounted as it is one of Star Trek's "odd numbered" movies, popularly believed to all be poor. Star Trek 3 suffers unfairly under this: through directoral flair it succeeds as a film in it's own right while still serving as an excellent sequel to Star Trek 2, and maintains the same high standard that film set. The cast all shine in their own moments (especially Sulu), and William Shatner is at his best - performing as well as he did in Star Trek 2 but with a meatier part. Spock may have died at the end of the last film, but here Kirk is forced to risk everything, and looses much. Perhaps Leonard Nimoy observed how Nick Meyer managed to pull so convincing a performance from Shatner in the previous film, because he's certainly never as good after Star Trek 3.
This DVD is a great improvement over previous releases - two dics gives you extras that are always informative and for the most part truly interesting. The directors commentary gives Leonard Nimoy the chance to speak with his directors hat on for a change instead of as an actor, and gives good insight into what it's like for an actor to direct for the first time - it makes me want to buy "Three men and a baby" purely to see how his experiences develop.
All else that can be said is that the sound and picture quality are excellent throughout (especially considering how old this movie is), as are the discs animated menus. Oh, and hunt out for the easter egg - it contains probably the best documentary on this two-disc set.
