Star Trek III: The Search for Spock (1984)

You Klingon bastards! Kirk gets personal.
It is what it is folks, it's a good honest Star Trek story, it beats a real emotive heart and although some may decry the lack of blistering space battles, or end of the universe peril scenarios, it's an essential film for dealing with the protagonists we know and love.
Into the mix here we have our favourite alien enemies The Klingons (led by the oddly cast Christopher Lloyd), Spock's father, Sarek, who adds grace to the story, and crucially Kirk gets an emotional kicker. While elsewhere hardcore fans get a big surprise with the beloved Enterprise.
It's of course merely a set up for the next (and delightfully great) instalment of Star Trek IV: The Voyage Home, but on its own terms this stands up as one of the better character pieces in the series. Due in no small part to having Leonard Nimoy directing it because he shows care and thought about a subject he obviously knows quite a bit about. 7/10

Picking up closely from the second film, this sees our crew of adventurers defy their superiors and steal the Enterprise in an attempt to rescue "Spock" from the Genesis planet. This is probably the best of the films for both DeForest Kelley and James Doohan as they both have some more of the play than normal; Christopher Lloyd is on fine form as the Klingon commander "Kruge" and there is plenty of phaser action to keep us all entertained. Not quite as well put together as the "Wrath of Khan" but it continues to develop the characters in an entertaining fashion.
