What it’s about: Humanity is on the run. Over a century ago, civilisation was destroyed by a species of Lovecraftian abominations known as the Gauna. The only survivors are crowded onto a single colony ship travelling through the void. Short on resources, they’ve nevertheless survived in isolation for over a hundred years, mining asteroids and maintaining constant combat readiness, just in case. Many sacrifices and adaptations have had to be made, but the people are safe and secure. Until, one day, the Gauna return.
Why you should watch it: It’s a great mecha show, and does a good job of balancing exposition and world building against more conventional action scenes. The show manages to maintain a high state of narrative tension without dragging things out; overall a fantastic translation of the original manga. It helps that it has an excellent soundtrack and sound design behind all of the action taking place on screen.
Caveats: The animation is largely computer generated. For the backdrops and action set-pieces it works really well, but the characters’ faces end up looking alien and mask-like. It gets better as the series goes on, but it’s pretty jarring at the start
Similar works: The show is essentially a blending of Attack on Titan and Battlestar Galactica, with mecha space-battles thrown for good measure.
