Admiral Kirk and his crew at the bridge seem to be trying to enter a very dangerous mission when they try to steal the institution that has stopped its activity to return to planet Genesis. Now, you must search for Spock's body, so that the flesh and spirit can be returned to Vulcan simultaneously. Over time, it became clear that the spirit of Spock existed in the mind of his colleague.
These are classic directorial occasions, and Nimoy rises to them with fervor, in effect beaming his film up onto a higher pictorial plane than either of its predecessors.
...a somber, mournful installment of the Star Trek franchise. And when the defining trait of your series is dullness, this isn't exactly the best strategy.

This is a good but not great Star Trek movie, a sort of compromise between the first two.
This 1984 film's few and unimpressive special effects evidently qualify it as science fiction, but the genre it really belongs to is the male weepie: there hasn't been a gooier buddy romance on the screen since Joe Buck took Ratso Rizzo to Miami.
"Star Trek III" has a genuine spirituality, and, at its end, you may be surprised, especially if you're not really a Trekkie, to realize how moved you've been.
