I went into Blame! knowing absolutely nothing about the movie, with my only knowledge being a single trailer along with knowing it was a sci-fi movie alongside the animation company being Polygon Pictures.

I guess Polygon Pictures by this point is pretty well known for the unique cgi style they use in most of their movies. But even though it was cgi, I never had any issues with the visuals of the movie. Every single scene to me looked incredible, even though they didn't use a massive color palette. Mostly greys and blacks for every scene, but then combined with flashes and dots of color in certain scenes. To really bring out specific parts of the scenes and help to change the mood of the scenes.
The only thing I feel will turn people away is the cgi characters not always being every-bodies favorite. They do require a small amount of time to get used to, but once you do they look fine.

While the visuals were stunning, they were assisted an insane amount by the music and sounds that appear in the movie. Just the right amount of atmospheric building sounds and music in the background, to help propel a slow scene of characters walking through a bland grey hallway into something much more impressive. Meanwhile it does a great job of building up for fight scenes, or slowing down when necessary. But never once felt to me like it was overpowering or imposing, and instead helped to capture the tone of the scene perfectly.

To be honest, the characters might be the weakest point of the movie. We have a village full of half starved people fighting every day for their lives. Who are just trying to find enough food to keep living. A Mysterious traveler Killy who wonders into the village, and proceeds to assist the villagers to survive in this world. Alongside a strange robot Cibo that never really gets explained.
And that is kinda the weak spot, none of the characters really get explained. Sure some of the it can be understood without much story or character building. Like with the villagers, most of them don't really require more knowledge and information to be dedicated to them. The basic idea of the villagers is simple, they require a safe place to live in which they aren't hunted constantly. With only a couple villagers playing large roles, but those roles are dedicated to protecting the village, or protecting people who could help the village. Some rather unfortunate romance between some of the villager characters, but it is never the main point, so it never really does get any time dedicated to it if it isn't part of the larger plot points.
The Mysterious traveler Killy, who is a strong silent character. He doesn't speak much, and doesn't really hold conversations with anybody. Merely speaking in order to gain the necessary information needed to further his goals and mission. But even though he doesn't speak or show emotion really, he has moments that you can tell he does care about the villagers that he ends up helping.
Then we have the Strange Robot Cibo, who never really goes from just that, a strange robot. Well robot, or human, not really sure and never explained or had any time dedicated to even trying to question it. Another kinda quiet character who wants to achieve the same goals as Killy, and therefor just happens to decide to work with Killy. But even Cibo, with how emotionless and giving off a feeling of simply going through the motions of talking with the villagers as something to do without any meaning, still has moments of wanting to assist the villagers.

Both the world and the story seem like large massive questions, that never get explored in this movie. And instead seem fully willing the leave the audience questioning what is going on in this world. The same can be said for the story, or at least the larger story that obviously is occurring. While the movie seems to just be a diversion from the ultimate goal for Killy and CIbo. The story contained in the movie is the villagers trying to find more food and information about the world that could help them stay safe. And the larger mission of Killy and Cibo just happen to be a good way to attempt to achieve those goals of finding food. But the larger story of Killy and Cibo is never a focus, and never fully explained. Just that they are trying to figure out the secrets and restore the city, and one part of that goal is tracking down humans who might have a gene that is incredibly important.

Even with the story and world lacking in development and leaving you with questions, along side the characters who never got developed. I enjoyed every second of this movie, and would love to see more from the world. Just what I saw intrigued me as to the larger world and story, and made me wish to get more to this story.
