Except the Skrulls becoming a malevolent force due in large part to the actions of the Kree isn't the result of some "Berkley" poli sci prof. critique of modern geo-politics... It's the story as it's been in the comics for decades as developed by Marvel comics creators from Stan and Jack to Roy Thomas.
From the wikipedia entry on 616 Skrull history:
Eventually, the Skrulls developed long-distance space travel; a great tour of the universe was undertaken, led by Emperor Dorrek. Finally, the Skrull delegation reached the planet Hala, home to the then-barbaric Kree and the peaceful Cotati, and held a contest to determine which of the races would represent Hala to the Skrull Empire. Seventeen members of each race were taken to different uninhabited planetoids where they were left with sufficient supplies for one year. At the end of that period, whichever group had done the most with themselves would be adjudged the most worthy. The Kree were taken to Earth's Moon where they built a great city while the Cotati were taken to another barren world in a different solar system and used their abilities to create a beautiful park. Realizing that the Cotati were going to win, the enraged Kree killed all the Cotati. When the Kree revealed that they had solved the question of who would represent Hala to the Skrulls by destroying their opposition, the Skrull delegates were appalled and vowed that Hala would forever be banned from their circle of favored worlds—so the Kree massacred them as well, took over the Skrull landing spaceship by force, and developed their own technology from it.
Because of the immense distances involved, decades passed before the Skrulls learned of the Kree's activities. By this time it was too late. The Kree were now advanced and audacious enough to attack the Skrulls in their home galaxy. During the millennia that followed, the Kree aggression forced the Skrulls to become a militaristic civilization, and the Skrulls eventually developed the vicious streak needed to conduct intergalactic war. Their entire culture was remade in the warrior image.
So... No this actually not something new. It's adapting this aspect from the comics, just more compact for the purpose of fitting it into a less sprawling medium narrative wise than the comics.
Hm, that history is actually pretty interesting. Happy to concede the point, wasn't personally familiar with the actual origin of the grudge between them there.
I dunno. Personally, by this point, the 1990s, I do need the Skrulls to be bad-natured conquer-y mofos though, especially if they're indeed being set up as a big threat going forward in phase 4. That doesn't mean the Kree should be "good guys" or whatever, of course not, they never have been. I just think you can push the Skrulls-as-victims thing a little too far too, they've gotta have that infiltrate-and-conquer-and-spread-throughout-the-galaxy thing as a part of who they actually are. That all gets ****ed up if it's all as basic as "the Kree personally affronted the Skrull's leader Talos, in very recent history". Mar-Vell being all kum-bah-ya and trying to help them out with tech against Kree orders is just fine, that's all in-character. I just mean like more broadly, I hope that's not
the reason the Skrulls are out there going all Genghis Khan on everyone, like they were just sitting around hugging puppies before the Kree decided to whack Mar-Vell and punish Talos.
Not gonna pre-judge it though, making one's mind up in the abstract without having seen it is irrational. Mixing things up for the movies in general isn't something I'm opposed to on principle, actually love thw IM3 twist and that type of thing. And those recent interviews with Mendelsohn where he describes the Skrulls as "these really tough lizard-pigs" or whatever is encouraging, makes them sound more like these scrappy fighters who were a ticking time bomb and now have a supposed excuse to go all kill-crush-destroy on the galaxy. If it's more like that, fine. Again, context matters, this all just might be fine.
EDIT: Regarding Carol being the inspiration for the Avengers rather than Cap, no problem there, that adds up. I think so, anyway - is it directly referenced in Avengers that Cap's WWII exploits were what got the idea kicking around in Fury's head? I can't remember anything like that.
This works though. Nick has personal experience with Carol, and while he's obviously aware of Captain America 50 years earlier, that's probably not front-and-center in his mind at the time. The program's linked to S.H.I.E.L.D., he knew Carol in hsi S.H.I.E.L.D. days, she's a million times more powerful than someone like Steve anyway....
Don't see the problem there, personally. Steve can sort of be a part of Nick's thinking in a broad sense, but his experience Carol (defending the Earth against extraterrestrials no less) is what spurred him to start laying the groundwork of making a team a reality. Takes 15 years to actually pan out.
