I think they miss the good that came out of the era. Superman's death brought Mongol back into play even for a little while. A completely underused Superman villain. Hank henshaw AKA cyborg Superman followed up on a story that not many knew about and gave a villain that had interesting possibilities. We got the return of another piece of Superman's history, the eradicator who has changed and evolved since then. And we got fan favorites. John Henry irons AKA steel and Connor Ken, AK Superboy. Emerald Twilight gave us a setup for parallax in the introduction of the rest of the emotional spectrum. I don't think it's nostalgia glasses for most people. But I think seeing where some of these story threads have ended up going in the current day and age. Makes them appreciate the stories more because they can look at them with a new pair of eyes and not just the '90s edgy nostalgia glasses

If you read the previous chapter is not actually a problem. The divine trees are speaking about love and it's effect on intelligent beings. This fits in just fine. This is almost like someone complaining about the Sauske retrieval arc and saying why is every one going all out to save him. It makes sense in the context of the story and the world and is a strange thing to complain about.

I am concerned about the book. Marvel already has a bunch of great characters and teams that get left behind. And they keep making more. A good example is the New Warriors who at this point should have been as popular as the Titians. But you barely see them here and there. If this teams bombs the book will be of the shelves in two years max and you might see one or two here and there.
