Kamisama starts with such an interesting premise and loads of potential. A destroyed world that god has abandoned where the living and the dead have to live together. The world is a desolate wasteland where the remnants of humanity both living and dead have created their own insular societies. It's a great premise, much like Kino's Journey it's a chance to explore different aspects of humanity in an extreme environment. Unlike Kino's Journey, Kamisama never makes use of its premise. Instead it keeps throwing up new ideas and new characters without bothering to develop any of them adequately.
There isn't really a plot to this anime, instead it's split up into a few different arcs chronicling Ai's journey through this wasteland world. The story arcs themselves are rushed and not very well developed any deeper themes are lost in a morass of bad comedy and even worse character drama that obscures any greater point to the people/societies that Ai meets along the way.
The problems with this anime start with the very first episode. It starts with a bleak somber tone that is immediately ruined with silly comedy and the overly cute main character being cute just for the sake of it. It's immediate shown that she is very naive, but instead of having her learn from her experiences the anime seems to actively encourage her naive ideals and then has her push them on other people. Worse yet, anyone that doesn't buy into her naivety are always shown to be misguided no matter what their reasoning is. It's quite sickening to watch her preaching her empty words and then treating them as meaningful in some way.
The firs arc is very rushed, and yet very glacially paced where I didn't feel like much of anything was actually going on in the first two episodes only to have the third episode be a hilarious plot hole filled cheese fest with a saccharine sense of sentimentality. That third episode was the one where this anime became really unredeemable train wreck. The story of Ai and her father makes little sense there are so many coincidences and stupid little inconsistencies it boggles the mind really. Her father is carrying around a picture of his wife and child but somehow doesn't recognize Ai and even worse Ai sees the picture is somehow unable to recognize her mother until the very last second. It's beyond stupid and the only reason is like that is to create false tension when there shouldn't be any. Again and again the character's actions don't follow any sort of logic but instead just serve to move events forward.
The second arc is an even bigger sin. It starts out well. It actually uses the premise of the series. Ai finds a city of the dead. A society of dead humans for dead humans. Exploring the city and how these sentient but slowly rotting corpses live their day to day life would have been very interesting. The dead in this world retain their memories and reasoning capacity for all intents and purposes they are the same person they were when they were living. However, before even starting to explore this premise the show derails into stupid drama involving a princess and her tutor. There's also a subplot with the tutor that involves magic and a bunch of other things that don't fit in with the series, including a strange he/she hybrid thing. All of this distracts from the premise of the series. Instead of playing out as a dark fairy tale to explore humanity, it becomes all about the boneheaded drama, and even the drama is ruined by the stupid comedy moments. The climax of the arc involves Ai naively getting involved with the princess's life and trying to force her beliefs onto the princess. Nothing gets resolved other than Ai meddling where she didn't need to.
The third arc is where things really go off the rails as at that point Kamisama stops pretending to even care about its own premise. Instead Ai finds herself at a Professor Xavier's For Gifted Youngster only with forced labor instead of learning mutant powers. This arc is barely even worth talking about. It involves an escape plot that several of the students had legitimate reasons for not wanting to escape back into the destroyed wasteland of the world where they were unsure they would be welcome anywhere. Ai however once again badgers the students that don't want to leave basically making them feel guilty until they decide to leave rather to listen to anymore of Ai's whinny ranting.
The third arc introduces the characters for the 4th arc which once again has nothing to do with the premise of the anime; instead it throws in an entirely new concept that doesn't gel with anything shown previously. However, instead of talking about the specifics of that arc, I'll say that it made the one theme Kamisama has very clear. The anime is about dispelling illusions or people's delusions, or at least it wants to be. However, the way the anime goes about it is very offensive. Given the situation of a lot of the characters; they might be living in a situation that they have to tell themselves is okay, but when the only other choice is to live in a post apocalyptic wasteland were the few societies are small and rather insular, it's pretty arrogant to tell people that they just need to buck up and deal with it. The people that Ai comes across are living happy little existences for the most part so who the fuck is Ai to come along and them "no,no, no, you're living the wrong way." And the thing is the anime totally supports Ai. It never takes into consideration other people's view point. Yes, the students at the school were forced into labor, but for the most part they were taken care of and they were unsure about being accepted anywhere because of their special abilities. They were comfortable at the school with their own relationships, but Ai told them they were wrong to want to live like that. And that fucking pisses me off. I hate her preachy holier than thou tone and I hate that she meddles in people's lives telling them how to live. Especially when she talks in such a naive way with absolutely no substance to anything she says. Her words are all meaningless platitudes. She claims she wants to save the world but she never defines what that actually means. It's like whatever she does she justifies it as part of her naive desire to save the world. Save the world by doing what? Forcing people out of their happy existences into wasteland of the word? Are they supposed to thank her for that? Is that going to make god come back? Fuck, no. She has no plan or idea of what she's talking about.
Ai seems to get her naive idealism and meddling nature from her father Humperpiety Whateverthefuck. Humpandpump has this whole belief that he should just kill the dead because they are being delusional, and he just plain doesn't like it. Honestly, fuck this character. Humpanddump goes around destroying the dead who are just trying to get along in a world that won't let them die. He can't even put them to rest, just tear them apart so they can't move. It's beyond cruel what he does and yet the anime treats it like a good thing. As Ai while not destroying the dead, takes on his attitude that people should live the way she wants and anyone that doesn't is wrong.
The rest of the characters in the anime hardly matter. The other people that travel with Ai aren't particularly interesting, get little to no development and are mostly pushed to the side. It seems like they had their own stories but they got cut out of the series for more of Ai's horseshit. The single arc character never get much of a chance to develop and they barely get time to give any kind of argument with Ai's beliefs, instead just getting pushed along in her direction. The characters from the last arc Alis and Dee get a bit of screen time. However, Alis is as single minded as Ai and while Dee tries to provide a counter point but her voice is drowned out in the anime. She's ignored to the point of being irrelevant until the very end and a retarded twist makes her change her mind. The last arc is also the most fucked up because the people in it are living a happy existence that they chose to wish for, but nnnooo, that's not good enough. They are doing it wrong because Alis and Ai say so. And to that I give them a hearty fuck you. People should be able to chose how they want to live and as long as they aren't hurting anyone there shouldn't be any problem with it. Instead Alis and Ai are forcing these people to go into a world that may very well may not be able to sustain them. It may be doing much more damage than good.
The art and animation are the only high points of the anime. MADHOUSE gave everything a very nice look. The OST is pretty forgettable. I doubt anyone will be listening to it outside of the show. The voice acting isn't bad but Ai's shrill voice will probably start to piss you off as you listen to her non-sense drivel over and over again.
Overall I hate this fucking anime with a burning passion. Not just because it wasted its really interesting premise, but because of it's stupid preachy tone which really just tries to hammer home it's own stupid message with no substance. Avoid this shit like the plague.
