One thing I like about Top Gun (1986) is how believable the development with Ice and Mav's dynamic is.
I've seen a lot of the "Rivals suddenly become buddies after traumatic event together" in media, but I don't think I've seen it done better than in Top Gun. Mostly, I attribute it to how much build up it has.
Most of the time, the 'Rivals' hate each others guts throughout the entire movie/series and then they go through an extremely traumatic event that binds them for life and shifts their entire concept of each other. Ice and Mav never once changed how they saw each other, it just changed their understanding of it.
Ice saw Maverick as dangerous and Mav saw Iceman as stuck-up and commanding. And they weren't wrong, by any means.
From the beginning, they have tension between them because of how different they are. And it ends up in the audience seeing Ice as the 'Antagonist' because that's how Mav sees it, and we're seeing it from his perspective as the protagonist. But Ice was never inherently wrong, in fact he was right.
Other than his first scene, Iceman always has a point in what he's saying. He's criticizing Mav, not insulting him. Sure, he does it in a brash way because masculinity, but he's not trying to insult him, he's trying to knock him down a peg and wake him up to reality. All Ice wants is that he starts to act as a team player, start caring about everybody's safety AND his own, rather than being reckless for the sake of being reckless. But Mav sees it as an insult because he can't process criticism in a healthy way (due to how he grew up). The same thing happened with Charlie, for the record.
And so the strife between the two begins. What I like about it is how it bleeds out of them over time, becoming more settled as the movie goes on. In the locker room "You're dangerous" scene, the tension is palpable. It's obvious they're agitated by each other, and feel the need to prove they're the correct one.
If you pay attention, this whole... demand for superiority goes away as time progresses. They're fine with each other's presence, it's not like they're constantly at each others throat all the time. In the shower scene, Ice dropped all of the aggression and competitiveness from his tone and is instead just laying out what he thinks. He's not undermining Maverick, he's not lecturing him like a child. Iceman is just telling Maverick exactly how he sees the situation in hopes that it would make him realize what the fuck he's doing, but with little hope that it'll actually work.
That doesn't mean Ice is always correct either, he doesn't understand why Mav acts the way he does, thus fails to take into consideration the emotional trauma behind it. Which only causes even more strife.
The entire time, Iceman isn't being a dick for the sake of it, he just wants Mav to stop being stupid (by his standards). And Maverick doesn't understand it because all he gets from what Ice says is insults.
Maverick isn't good at understanding what people mean to say if it's implied, you need to say it to his face. This is the reason he stayed quiet in the shower scene, because Ice finally laid everything out in simple words that he can understand without making it sound like a dick-measuring contest.
Thing is, the tension mellows out. At the beginning, you could see the tension and cut it with a knife. By the middle you can see them getting used to each other without jumping to constantly trade jabs (namely: the volleyball scene, it's just a bunch of guys being dudes, and the scene where Charlie says that Mav flew recklessly in front of the whole class, Ice doesn't comment on it in any way). Over time, they've settled down into their tension without needing to address it all the time.
And the tension between them is still there.
Just because Goose isn't there anymore, doesn't mean their whole dynamic vanishes all of a sudden. You can see their hesitation towards each other (especially Ice), and that's great! It demonstrates that Goose dying doesn't magically resolve their problems with each other in solidarity.
Ice tried to give his consolations to Mav, and is awfully awkward about it. You can see on his face that he wants to say more, but doesn't because he knows it's not his place given their history. And not much is said, but a lot it communicated. (Val Kilmer is a killer actor for this, OH MY FUCKING GOD BLESS THAT MAN)
Even in the graduation scene you can see how out of their depts they really are with each other. A stilted congratulations, that was it. But they're trying, and that's what matters.
A scene I think gets overlooked a lot is the scene right before the Layton, where Ice expressed his worries about Mav to Stinger, and Mav heard him. Because I feel like that was a shift that was more drastic than the Layton itself for them.
What Ice was doing in that scene wasn't doubting Maverick's flying abilities, it was his mental health. Sure, he passed the psych eval, but that means next to jack shit when in a real combat situation so close after his backseater dying. And Ice might be worried that he's gonna be left hanging, but with the way he was speaking I'm more inclined to believe he was more worried about Maverick's wellbeing than himself. Ice almost looked resigned. He knew it was gonna get dismissed because that's the military for you, but he still wanted to try to vouch for Mav to stay groundside, if only to keep his mind at bay.
But Maverick heard him, and as usual, he read it as an insult. He wasn't wrong to assume Ice didn't believe him capable of flying the mission, which wouldn't be a lie, but failed to realize that he had more than one reason to want Maverick on the ground rather than in the air. And for the first time, Maverick believes him.
Up until this point, Mav dismissed all of Ice's so called 'insults' because he was certain in and of himself. But now he isn't anymore.
And it affects his performance in the air. I'm not saying he was as shitty as he was at the start of that combat because of what he overheard, but I am saying that it certainly didn't help matters in the slightest.
So their weird 'stepping-on-eggshells' situation is all over the place by that point. Because they started to care about each other despite not being what one would call proper friends yet. It's establishing a potential friendship by implying that 1. Ice cares about Mav's wellbeing and 2. Mav cares about what Ice thinks.
On the ground, they have the wingman exchange, and their suddenly buddy buddy. Thing is, it wasn't sudden at all.
They've been setting this up the entire fucking movie.
Going back to what I said at the beginning: Ice thinks Mav is dangerous and Mav thinks Ice is stuck-up and controlling. After the Layton, they still think those things because they weren't wrong to begin with. What changed was that instead of seeing it as something that pitted them against each other, it was seen as something that simply was about the other, and that there was no changing it. It could be good.
Mav being dangerous could be good and Ice being stuck-up and controlling could be good, because those were just traits of who they were. By the end of the movie they didn't change how they saw each other, just how they interpreted each other.
And it was built up during the entire fucking movie.
There was a reason to why they acted the way they did with each other because of the stilted interpretation they had of each other. From rivalry to friendship (and perhaps more later down the line), it's glaringly obvious throughout that it wasn't a sudden shift, it was exponential.
That's why I think it was so well developed, because you could see it coming.
