I also wonder if The Raft had other levels/cells to it. [...] I'd think there'd be many floors filled with people needing that level of containment (which shouldn't extend to any of the ones captured except for maybe Scarlet Witch) and what happened to them when Cap infiltrated the prison?
Who else in the MCU would require that level of containment? Few of the movie villains have even survived. Let's do a rundown:
Obidiah Stane: Dead.
Whiplash: Dead.
Justin Hammer: Presumably in prison but not physically dangerous enough to merit the Raft.
Loki: Presumed dead. Actually impersonating Odin on the throne of Asgard.
Red Skull: Missing, presumed dead.
Dr. Zola: Died of cancer in the 1970s. Brought back as a computer program which was destroyed in a missile strike.
Aldrich Killian: Dead. Although I suppose some of his fellow AIM soldiers might have survived and been captured.
The Mandarin/Trevor Slattery: Was arrested at the end of
Iron Man 3, but I'm told someone broke him out of prison in one of the One-Shots.
Malekith the Accursed: Dead.
Winder Soldier: Currently at large.
Alexander Pierce: Dead.
Ronan the Accuser: Dead.
Nebula: Currently at large, and not on Earth anyway.
Baron Von Strucker: Dead, murdered by Ultron.
Ultron: Dead.
Ulysses Klaue: Presumably still at large.
Darren Cross: Dead.
Crossbones: Dead.
Colonel Zemo: In prison.
Abomination: It's been so long since I've seen
The Incredible Hulk that I honestly don't remember.
So, few if any from the movies that are still alive, in custody, and merit the Raft. I don't know if there are any from
Agents of SHIELD that fill out the numbers.
I can see Wakanda remaining a signatory, if only as a means of being in on any decisions or actions taken by any Sokovia Accord supporters among UN members.
Which kinda proves Black Widow's point: At least with one hand on the wheel you can still steer.
I was a little surprised Crossbones got crossed off the list so quick but so what?
That keeps happening. I was similarly surprised that Baron Von Strucker got killed off so quickly (and off-screen at that) in
Age of Ultron. And after his teaser appearance in
Thor: The Dark World, I expected the Collector to have a much larger role than he did in
Guardians of the Galaxy.
The Red Skull has whacked them since Amazing Spider-Man Annual 5. Circa 1968.

In 1968, they were not S.H.I.E.L.D. Agents, that wasn't revealed till 1997.

So, not killed by Hydra.
My brain farted.
The Red Skull was on his own kick, and killed a couple S.H.I.E.L.D. Agents.
So, before they established that the Parkers were SHIELD agents, what was the Red Skull's supposed reason for killing them?
If you really want to accept a seriously continuity jiggle, try reading "Trouble". That's the Book that says that May is really Peters mum, but at the time she was too young and irresponsible to look after a baby.
You're welcome.
*groan* Yeah.

I've never read it but I read a synopsis of it.

Some things just need to be burned.
Yeah. Now, Tony was off the deep-end in this movie; in fact I'd say his actions in this movie sort of "damage" his character (in a "good", dramatic, way) given his behavior. It's hard to really "root" for him during the airport battle because he's just being an off-the-deep-end asshole in the way he talks to his supposed friend, Steve. (Which, I don't think the previous movie did a good job as setting them up as "friends" more than they were co-workers who tolerated and respected one another on some level.) I think by the time he encounters Steve in the Hydra base he's come back a little bit and even in the final scene as he ignores Ross's call he's sort of on track again. But for a good part of the movie he's probably close to the true antagonist in the movie.
But his reaction to watching a video of seeing Bucky kill his parents is hardly something we can fault him for, the loss of his parents is something he's wrestled with his entire adult life and here he watches video of a man murdering them. (Though did he really think they just died in a car accident? Surely when their bodies were found autopsies and such would have revealed they died from being attacked and not from the crash.) He cannot be blamed for reacting with raw emotion towards the man who did this and not think about TWS's brain-washing (which, how much of that did Tony know about at this point?)
So, yeah, Tony was a human being and got mad a person who killed his parents.
Apart from the fact that he's a genius billionaire inventor, being Tony Stark kinda sucks. Despite all his wealth & power, few things seem to go his way. He nearly died in a bomb blast and only survived by putting a giant electromagnet into his chest where his sternum should be. He got captured by the Ten Rings and discovered that they were using his own weapons against innocent civilians. He failed to save Yinsen during their escape attempt. Obidiah Stane, his surrogate father, turned out to be a jealous, murderous lunatic who tried to kill him multiple times. The miniature Arc-reactor in his chest nearly killed him with palladium poisoning. He had a strained relationship with his father, made worse by the fact that people like Nick Fury & Steve Rogers keep talking about what a great guy Howard Stark was. (Tony should try hanging out with Hank Pym some time. They may not have much in common but at least they're both non-members of the Howard Stark fan club.) He suffered PTSD after the Chitauri invasion of New York. His attempt to create a benevolent world-saving A.I. turned into a genocidal murder-bot. He feels guilt-ridden about all of the collateral damage that the Avengers & Ultron have caused. His attempt to make amends by subjecting the Avengers to oversight fractured the team in half. The resulting battle crippled his best friend. He & Pepper broke up. He discovered that his parents were murdered and then fails to avenge them.
Tony Stark is a popular enough character that it makes sense that they would keep bringing him back in
Age of Ultron &
Civil War. But I'm still kinda bummed that he didn't get to keep the happy ending that he got in
Iron Man 3.
Did Cap seem "over-powered" a bit in this movie? I've never taken for him to be "super-powered" but just "absolutely powered." He's at the peak of human endurance and physical strength and maybe a nudge better. The fastest a person has ran a mile is 3m43s. So, Cap can probably do it in 3m30s. Maybe 3-minutes flat on a good day.
His stamina, endurance and healing are all "peak" too, again giving the movie world a good deal of latitude on what that entails.
But in this movie... Well, see him acting like Superman. The biggest thing for is when he's stopping the helicopter Bucky is trying to escape in. I don't care how strong Cap is, he doesn't weigh more than a helicopter and certainly not more than a helicopter taking off when it's providing enough lift with it's rotor to achieve take-off. But we see Cap run up to the helicopter, grab the skid, and tug it back to the ground. Which.... No. If the helicopter is lifting off the ground a 200lb man isn't going to just tug it back to the ground, he's going with it. Same with when we see cap grabbing on to the skid and rooftop helipad. He's straining, sure, but he's pulling a several-ton heavy helicopter, achieving lift, towards him and preventing it from going away.
That seems a bit strong for Cap who, again, isn't supposed to be strictly "super" powered, and there's not enough hand waving in his abilities to "buy" him the leeway. I mean, strictly, Superman wouldn't be able to "pull" a helicopter to the ground if it's got lift (again, Superman weighs less than a helicopter. He's going with it no matter how strong he is pulling it back to the ground) but there's enough mumbo-jumbo in his powerset it's argued that some aspect of his flight, strength, sun-powered powers allows him to "fix" himself to the ground in order to pull the copter to the ground and prevent it's takeoff. (He's "flying in reverse" in other words.)
Some of that bothered me too. I sometimes think Hollywood has no sense of physics at all. Now, since I don't know exactly how strong Captain America is supposed to be, I was OK with the latter part where he was holding the helicopter with one hand and the helipad with the other. But when he was just standing on the ground pulling the helicopter down, that shouldn't have worked. He's not that heavy. He should have gone up with the helicopter. (There's a similar scene in
Underworld: Evolution that bothers me, where Markus uses a rope to pull down a helicopter even though he's not that heavy. The effect should have been for him to climb the rope.)
Superman is slightly different because he could provide some kind of reverse thrust through his flying powers. (I'm convinced that he generates some kind of anti-gravity field that he can transfer through touch. It's the only way that the scenes with him flying with Lois Lane in the 1978 movie make any sense.)
True, but then wouldn't Tony have access to SHIELD's/HYDRA's info after JARVIS broke into the Helicarrier's computer with his little thumb drive, or when Black Widow released the HYDRA files? (Though, I guess ZImo apparently needed Bucky to tell him what happened on that date. But I'm not entirely clear on why that's the case. If the files were too encrypted for him or if they weren't there. If they were too encrypted I'd think JARVIS or FRIDAY could've hacked through them.)
I doubt that Hydra would have kept extensive computer records of all of their many perfidious deeds on SHIELD servers. I suspect little things like doctoring autopsy reports would have been kept off the books; more of a handshake deal.
The Hulk, on the other hand would be team Cap all the way. Banner spent years being pursued by Ross, and there's no way he would ever submit to anything that gives the government control over him.
On the other hand, Ross said that, if they didn't want to submit to supervision, they could retire. Considering Banner clearly doesn't want to be found, that would seem like a sort of retirement. (I wonder if part of the Sokovia Accords says that there will be no further attempts to weaponize the Hulk or any similar gamma-based super-humans.)
Thor seems to be popular among Earth's civilian population (and Maria Hill *snicker*). But I wonder if Earth's governments would legally classify him as a soldier of a foreign nation.
Since he's technically crown prince of Asgard, would that give him some kind of diplomatic immunity?
