After the second movie I felt like this this whole story managed to achieve nothing at all. Japan wasn't changed, the couple wasn't reunified. Some neets got a better life. Maybe that was worth something but if was a pretty grand operation with quantum computers, missiles, people dying, and all the other jazz just to get a limited bunch of neets a more social life.

It would have been a good ending if Saki and Akira had at least got together, even if the grander achievements had been left at this level. Personal happiness should always be a worthy goal.
