The foundation of Isekai anime criticism is: Man makes anime, anime does not make man. Isekai is, indeed, the self-consciousness and self-esteem of artists and authors who have either not yet won through to themselves, or have already lost themselves again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce Isekai, which is an inverted consciousness of the world, because they are an inverted world. Escapism is the general theory of Isekai, its encyclopedic compendium, its logic in popular form, its spiritual point d’honneur, its enthusiasm, its moral sanction, its solemn complement, and its universal basis of consolation and justification. It is the fantastic realization of the human essence since the human essence has not acquired any true reality. The struggle against Isekai is, therefore, indirectly the struggle against that world whose spiritual liberation is Isekai.
Media escapism is, at one and the same time, the expression of real suffering and a protest against real suffering. Isekai is the sigh of the oppressed gamer, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the anime fan.
The abolition of Isekai as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their escapist illusions about their condition is to call on them to give up a condition that requires escapist illusions. The criticism of Isekai is, therefore, in embryo, the criticism of that vale of tears of which Isekai is the halo.
Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of Isekai disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Anime is only the illusory Sun which revolves around man as long as he does not revolve around himself.
I think isekai if well done can serve as a foil for some political point. Like in mark twains coneticut yankee. Or as an exploration of pre industrial conditions like in lets the darknes fall. Or as an excersice on development ecinomics likr in release the witch. Or ideally as a way to get kids interested in chemestry and mechanics.
What bothers me is that the protagonist comes from the modern world and has a hihgschool education. He/she presumably can do calculus and knows basic chemestry. Instead of relying on that they pull some magic bulshit.
Even in the previously mentioned ones release the wich has some problems with the chemestry. Mark twains protagonist has it too smothly and it is not realistic that his society progreses so fast. Also the medievals are not realistic.
I would like to se an isekai where the protagonist is a lib and tries to find lib solutions to the otherworlds problems succeds at first but then ends up making things worse for everyone.
I must confess i liked lord kalvan of otherwhen.
