I think the issue is we don't have really any idea of what the conflict is. It just shows them involving themselves throughout time to develop humanity, a few disasters, and then them in the present having a family dinner. We have no idea of the actual modern stakes.
This does remind me of something that I find kind of funny about the MCU these days and I know it had to happen, but remember when Iron Man was the only hero? I watched Iron Man again recently, and the movie hits a whole lot different after the modern MCU. Before you could kind of give it a pass when all you had to think about was there was a Norse god kind of hanging out in space and a super soldier stuck in ice, but now you have...
An Ant Man, fought in countless wars.
A society of sorcerers defending the planet.
An African super soldier since ancient times.
A galaxy spanning set of civilizations all intermingling, trading, and fighting.
A super powered hero from the 90s that can punch space ships.
Now we are finding out...
Humanity itself was crafted by super powered Eternals.
The entire timeline is under the protection of something called the TVA.
Like, honestly, I go back and watch Iron Man and just think "Right now there is a super powered woman traveling through space, an intergalactic war between the Kree and Xandar, a super soldier in Africa behind a technological dome, a society of sorcerers keeping out Dormamu, people outside time that are policing the timelines, and a bunch of immortals having breakfast.
Again, it all had to happen, you can't expand something from a single point in time forward indefinitely, you gotta work from the past too. It's just weird looking back on it, is all.
Now I can't stop thinking about what the Eternals thought when the Asgardians were defending Norway in the olden days, or how the greater galactic civilization ties into the nine realms, which are also just planets out in the galaxy. When Heimdall gets bored does he just watch the Kree and Skrulls exploding eachother? I might have to go buy more Thor comics someday.
