It's funny. I'm watching this movie and I can't help but feel like one of it's purposes is to show how NEVER and Quarks are infinitely inferior to the Gaia Memories.
I mean, look at all the experiments and defects that the those two projects have wrought? The Gaia Memories, even with their drawbacks, have merits that more than make up for those. There's only three Memories in this movie, and look how much more powerful those were than everything else? One was able to control a whole village because of it's power, and the inhabitants were actually more powerful than average humans. And it took another memory just to stop that Memory, despite not being able to succeed fully. That's because Gaia Memories are the 'Earth's consciousness' with a bit of tinkering from humans, which is definitely more powerful than purely man-made experiments like the other two.
Another thing is how scary Daido really is. He beat Kazu like he was nothing. Well, Kazu was not fully prepared to face someone else with a Memory like Eternal, and that Utopia's power is useless against dead people like Daido, who in turn has physical resiliency and combat experience like whoa because he's a NEVER, I guess he was at a disadvantage from the start. It really shows how Double was really lucky when he fought Utopia, who was even more powerful then because he was turned to a NEVER with Quark powers. Brrr.
All in all, this movie was very satisfying, because it answered questions and cemented the fact that Daido was not a totally evil person. Just a guy that snapped after being screwed over time and time again.
