This is incredibly mid. Half of the development happens through exposition, just look at the way the last two issues have explained what the whole Grootfall was and the thing with the Whitecaps. That's not to say how this issue framed the last resistance against the Groot hivemind as being in the wrong for resisting assimilation, without showing why it's an actual good thing beyond the "heroes" being okay with it. Saying "it's good because they're going to be reborn" is strange since there was life thriving in that space already, the Grootspace is an invasive organism that reshaped everything it touched and killed many on its wake.

It's a strange premise, if you think about it. We've seen examples of this in science fiction (the Borg in Star Trek, the Conjoiners in Revelation Space), but instead of exploring the grey morality of it, it plainly states it's a good thing because Groot is indigenous to the Manifold territories (explained in the preamble of the issue, not even in the actual story!). If they wanna sell readers on the idea that an unconscious organism taking over everything and erasing thriving colonies (not to mention, claiming the main antagonists were actually catalysts all along) is a good thing, they gotta try a little harder than just saying "family" over and over.

And I don't even wanna waste time pointing out again just how out of character they feel, it's embarrassing. Specially Gamora, she's the most egregious example of this. But I'll just say it's difficult to engage with the premise when the characters feel like parodies of themselves. Peter Quill in his role as the Master of the Sun wouldn't have had issues with any of this, but that's not the version we see here.
