I mean honestly out of all the properties that the Marvel Universe has: WHY considered the Eternals a movie ?

And before you speak of the Inhuman mess let me ask you all this: What is to say that Marvel cannot try again with the Inhumans ?

I mean they replaced the Hulk/Bruce Banner before and look how that turned out ? So why not the same for the Inhumans or at least mix them up a bit ?

Just WHY are the Eternals considered a movie property and not something more ...grounded ?
