I thought all in all Vol. 5 was good... The dogfighting was amazing although I was a little disappointed by the way both Nora and Ivanov died (killed by the bird-human).
At the end it wasn't explained what the bird-human was... is it a proto-devlin? Or something to that extent?
But it was obvious that AFOS was planted on earth to be revived at some point to figure out whether the earth is a peaceful place yet, it asked Sara a series of questions about the current state of the earth before it sings the 'Song of Death'.
At the very end Aries told Focker it is very easy to save the world, it's 'love' - this is total tie in with what Macross stands for, I thought that was quite well put.
One thing that was quite puzzling was why did Shin also disappear? Sara told him to take care of the Mayan people, but yet it would appear that Sara came back and took Shin with her...
I wished that they had both died when the Monster fired at AFOS, it would've been more fitting some how (now we have to wonder where Sara and Shin went, hmpf!).
Although another idea I got was that, well, Mayan's stars were robbed by 'technology' and 'civilizatoin', so Sara and Shin went to space to become the stars that will watch over the Mayan people..
I would look forward to a possible movie edition, that would tie everything in, and possibly offer some answers...
