Wow, Eternals is some weapons-grade nonsensium.
Marvel has had some bland ones, movies I'd give a "C" grade to, but this is their first D or F.
Lots of Marvel movies have a problem with hoards of nameless enemies, always robots or cyborgs of some kind, so it's OK to slaughter thousands of them in a PG-13 movie.
I'm still not sure what the hell those things in the first Avengers movie were and where they came from. Aliens? Robots? - usually doesn't matter though because you're interested in the rest.
Eternals has the same problem with bland, generic enemies, but in this one I also didn't care about the heroes at all, and couldn't tell who had which powers for the most part.
Power is a problem too... they're clearly not all created equally. I mean "I'm a really cool 3D projector person" could be useful, but it's not much compared to instant healing, mass mind control, super strength, speed, flight, eye-lasers, etc.
They put it out on Blu-Ray and streaming a few days ago. Odd choice not to rush it out for Christmas sales, but I guess they knew it wouldn't sell well anyway.
