Re: Star Trek III - great rewatch value
I think TWOK is quite self-contained, despite all the sequel hooks right near the end. It can definitely be watched as it's own standalone thing. TSFS on the other hand is very much tied to the events of the movie before it, and by extension it still hasn't wrapped things up by the end, necessitating a further sequel to finish off the story.
On some levels TSFS and TVH are more closely linked than TWOK and TSFS, even though TSFS is a direct follow-up to TWOK.
I agree. The shot of Spock's tube on Genesis is a nice teaser, but the film certainly could be viewed alone and enjoyed just as much without having seen the two subsequent movies.
