There is a HUGE plot hole in "Search for Spock". Why must Kirk return to get Spock's dead body from The Genesis Planet, and how did he know it was even there? When Spock's father comes to see Kirk and does the mind meld, Kirk is told that McCoy along with Spock's Katra (his living soul) must be returned to Vulcan so that both can find peace. How that Katra will be saved by the Vulcans is never explaned in the move. Next thing we know, Kirk and friends are stealing The Enterprise (best part of the film), and heading for The Genesis Planet. Kirk is never told that Spock's photon tube was found by Kirk's son David intact. So without that knowledge, why this out of the blue plan to head back to The Genesis Planet ? Last thing Kirk knew it that Spock's tube was shot in space most likely to burn up during entry into the Genesis Planet's atmosphere.

Another thing that bugs me, is the illogical comment made by Spock's Father when Kirk returns Spock's body and McCoy's Katra laiden brain to Vulcan. He asks Kirk "WHY" did he do this! "At what cost Kirk, your Son, Your Ship!" Umm, well it was this very same guy (Spock's father) who told Kirk that he "MUST" return to Vulcan "no matter the cost" only a few short reels before. How freakin' stupid! "Search for Spock" was a real let down.
