Again, it's simply futile to compare the movies with the TV shows. They're different stories told in a different format to a different audience.
You might as well be criticising an episode for only being an hour long or for having ad-breaks.
Revenge is not a commercial break. TMP, TVH managed to do it without revenge and they were commercially viable. It was an original story, and so was Khan at the time. This is a problem with fans' expectations.
You mention here about Khan being original as well as a tired old Ahab type story in another post. You do realize that TWOK and FC were both essentially Ahab stories, don't you?
Yes, I do. It was the first time that Star Trek had done a revenge story...ever. No one in the original series, 80 episodes, was out to get Jim Kirk because of a foul-up he had along the way. That's what makes it original.
Continuing, there's more to the story than that. We seem to forget that these movies have more than just one piece. What made Khan original was the elements of the story. For instance, exploring what makes Jim Kirk tick by showing him as a teacher. The two 5-year missions are over, now it's time to train the new recruits. The Kobiashi Maru (Japanese for merchant ships) was a way to show that Kirk "cheats death" and he's proud of that fact, even rewarded for it. Ever try to teach a child something that comes natural to you? This is real-to-life. That's one.
Two, Genesis and Khan are the results of technological advancement. Both eugenics (WW III) and and Genesis (as a bomb) are "peverted into dreadful weapon(s)." Being able to pick hair color and intelligence led to a race of Super beings. I refer you to the scene where McCoy, Spock, and Kirk all talk about Genesis. "Scientists have always been pawns of the military." This continues today. For instance, memory capacity in computers and robotics has led to drones today. In the time of this movie, it was talking about splitting the atom and turning that into a weapon, the A-Bomb and the H-Bomb.
Three, this movie talks about "life from death." Genesis creates a living, breathing planet. Spock sacrifices himself for the Enterprise crew. Kirk is constantly turning his circumstances of defeat into victory. Life from death.
Four, Kirk is seeking fulfillment whereas Spock has found it and is at peace. Kirk is brought back to life from his lack of purpose by his son, David, and losing Spock. Life from death.
"There's a man out there I haven't seen in 15 years who's trying to kill me. You show me a son that would be happy to help? My son. My life that could've been and wasn't. What am I feeling? Old. Worn out."
"It is a far better thing I do now than I have ever done. A far better...resting place I go to now than I have ever known."
"Is that a poem?"
"No, something Spock was trying to tell me, on my birthday."
"You okay, Jim? How do you feel?"
"Young. I feel young."
Khan is out for revenge and he's destroyed by his quest. What's his response to hearing he has escaped permanent exile, defeated the plans of Admiral Kirk, and has a ship to do with as he pleases?
"He tasks me. He tasks me, and I shall have him. I'll chase him round the moons of Nibia and round the Antereas maelstrom and round perdition's flames before I give him up!"
This is the first movie that does this. And it's a very rich and textured story in terms of theme and character. There is no comparison to the other movies.
FC has a revenge undertone, with Picard hell-bent on destroying the Borg no matter what, even at the cost of the lives of his crew and the ship.
Who said I liked "First Contact?" This would be the second movie, thank you for making my point. Star Trek: Nemesis would be number 3. Star Trek 2009, and what appears to be Star Trek Into Darkness, are 4 and 5. That's 42% of the movies where revenge gets the bad guy killed. And they will keep coming if we don't like anything else.
When I read about people who read into Star Trek as being all this glorious storytelling with intriguing morals, I have two things that come to mind:
1. "Spock's Brain", and
2. Nichelle Nichols once said, "We were going out there with high adventure. Of course it was peaceful exploration, but each week was a big adventure."
We are talking about good Trek, no? Not that every single episode was a winner, I mean, look at
Voyager and
Enterprise. Have I yet to bring them up in a good light? So the comparison to Spock's Brain is nothing to me. Honestly, I can't talk too much about it because I haven't seen it recently. But when Star Trek is timeless, it relies on the formula I describe. For all the complaining about Insurrection, it still has a thread every week talking about the moral conundrum. That's 14 years later. And that's the bad Star Trek movie that does this. Khan is the good one. So Nichelle Nichols can have her opinion, but
Patterns of Force,
A Piece of the Action,
City on the Edge of Forever, all these episodes dealt with some heavy material.
