Ah where to begin. Two episodes in, I was like, oh yeah! Lots of military scifi action. Animation is bad. Not really my cup of tea. But the premise of the story/plot is interesting.
Then the next couple episodes. The main character is weak. Though has tremendous potential. As always in japanese animé. Then the huge drama that comes with the Marnie character. Boy! This girl can cry! Again, thats japan for you. Want to inject a much needed drama? Make one or more characters wail and scream as loud as she can an cry an ocean of tears in the longest possible scene. I hope she gets eaten. But nah. She's the drama.
Then the rest of the episodes. Which are just filler episodes. Not much fun for me. But if you're a fan of extended loud crying in a very dated animation style, still a big no.
