The visuals and the overall concept are great. The world is believable and explorable. I wanted this to be as wonderful a film as it looked.
Trope alert:
They took the basic villagers against an overwhelming outside threat from Seven Samurai or Princess Mononoke, and the "system" seeing humans as the problem, from basically every science fiction film or book.
Cliché anime characters fill the world. The tough, spirited young teen; the wise old leader; the guy who is afraid; the wimpy young teen that everyone protects even if they die to do it.
Add the handsome, battle-scared loner who has traveled the unsurvivable depths of the city. He doesn't blink, he doesn't emote, he says about ten words in the whole film, yet let him in with his superweapon and let him walk behind you. You can trust him, he has intense blue-eyes and hero hair.
What made me go ballistic were the endless dramatic pauses. They could have tightened it by fifteen minutes. The standard time is running out, war is here, people are dying in horrific explosions. Oh, I know, let's walk slowly to do the only thing that might save everyone from a gruesome death. Cue the extended standard hero fight.
Other characters stop to stare at each other or talk. If our base/home/village is being overrun and you stop and want to talk about your loss or tell each other about how much you love them, I am going to slap you until you wake up.
Hint: If you come to a vast factory that can make hundreds of football stadium-sized batches of anything in a few seconds, how about creating some automated weapons systems, powerpacks, weapons, vehicles, or hover tanks? I understand that is too easy. If your plot is destroyed by something simple, then your plot is too weak.
Here's my suggestion. These films take years of incredibly hard work by thousands of extremely talented people. Several months into the planning, ask some of your staff if the plot or characters reminds them of another film. If so, change it or you risk this becoming another cookie-cutter trope anime film.
