How can you decide that this isn't macross. I think Kawamori decides that, since it's his creation. Did you ever think that perhaps you missed the message of every single macross series there is? Sure, things have taken a bit of a strange turn, but I think the problem that most people have with the later macross series is that you're all just so resistant to change.
There's absolutely nothing wrong with Macross Zero. I think it fits in perfectly with the theme of past macross series. And yes, I have seen and liked Macross 7. I hated it for about 10 episodes, but then let myself go and found I enjoyed it, despite the spirita strangeness.
Macross Zero is about showing the power and force that exists behind the scenes in the original TV series, movie and macross plus.
Kawamori is evolving the story, coming full circle. He shows us HOW it is that a single song can turn the tide of a war. Macross 7 shows how music affects people in the macross universe, and Macross Zero explains how that kind of talent and power came into the human race. Macross is not just about mecha. If that's what you think, you've totally missed the point.
Just accept it for what it is, and stop whinging about it because it's not what YOU want. Macross 7 and Macross Zero ARE. Deal with it.
Kawamori has always been a good director in my opinion because he goes against the grain. He tells the story he wants to tell, not what other people want to hear. And that's the way it should be. Macross is his creation, and his art. Who are we to tell him how to make it?!
