UPDATE:
The final act of the movie was so beautiful, I barely can put it into words. If only this method of storytelling had been more relative in the television version, it would have had a better chance. "Dancing in the Moonlight" is now my new favorite Walkure song with his disco homage and playfulness between the singers. Also, Kaname gets more time in the spotlight given how Messer got a more memorable and honorable sendoff both in his death scene as well as the funeral where the art department really outdid itself on the jellyfish taking off into the air. As a matter of fact, the animation department aside from that incompatible 3D computer/2D concert where Freyja debuted definitely deserves all the praise in the world for giving us the gift of spectacular visuals in the mech combat as well as the final battle concert where Mikumo finally breaks free of her Mary Sue/artificial human self and lets herself be inspired instead of usually being the one who gives the inspiration with her songs. Overall, outstanding compilation Macross Delta story and would definitely watch it again!
