Factual error: The "whaling boat" is too small to function as such. It isn't large enough to hold a fin, let alone disassemble a humpback whale.

9.5/10.The best Star Trek movie after Wrath Of Khan.My favorite and a movie with a pretty good environmental message.I liked the idea of humpback whales needing to rescued to save earth of the future with their advanced technology being useless.Here it seems like the Star Trek crew learned the past can sometimes be helpful to the future in the most unlikely of ways.It had a good blend of the sci fi we've become accustomed to with this franchise with humor mixed in such as McCoy curing a kidney dialysis patient.I would say this is the movie they had the most fun working on because it doesn't seem to bear signs of pressure anywhere the way the first two did.I viewed them and could see signs they'd been under tremendous pressure.Here it's a fun sci fi romp with Catherine Hicks being one of the best love interests ever in the franchise for William Shatner.I would gladly post this on a list titled "100 best Science Fiction Movies Of All Time."

Spock: Your use of language has altered since our arrival. It is currently laced with, shall we say, more colorful metaphors, "double dumb-ass on you" and so forth.
Kirk: Oh, you mean the profanity?
Spock: Yes.
Kirk: Well that's simply the way they talk here. Nobody pays any attention to you unless you swear every other word.
More trivia for Star Trek IV: The Voyage Home
Question: What exactly was Scotty's reason as to why giving the Company boss the formula for the one inch glass wouldn't alter the future? He gave a brief response, but I honestly can't think of any reason why it wouldn't do any future damage.
Chosen answer: Scotty says "Why? How do you know he didn't invent the thing!" If the man was in fact the inventor, this would only cause a slight causality loop problem - he "invents" it because they gave it to him, but they only know it because he "invented" it. However, since Sulu said earlier in the movie that it was about 150 years too early for transparent aluminum, it would seem they do know this, so it wasn't a smart thing to do. Of course, the real flaw in the plot is that they need the tank to be transparent at all.
Answer: The crew is resigned to the fact that their mission forces them to alter history in some fashion or another. McCoy just wants to acknowledge the gravity of their actions before they go ahead and do it, and Scotty's response is a cheeky way of reassuring him, "Hey, maybe it won't be that bad."

Answer: They only give him a schematic of the molecule. The man even says, "It would take years to decipher the matrix", or something like that.
