I align myself with the average of the opinions that have appeared so far on filmamo, but I add my opinion, which would be in favor of an even higher rating. For two considerations, one on the story and the other on the setting. For me the story is that of the maturation of a newborn's brain on an adult's body. The adult has all the impulses of adults, the brain tries to adapt. In other words, feelings align with the brain, there is no predominance of reason over passions. In other words, becoming fully adults does not mean having to mortify feelings, but means being able to manage them together with the intellect. We are not (fortunately) in the presence of a treatise on evolutionary psychology, and there are probably exaggerations on some traits of maturation (sexuality) to the detriment of others, but for me the overall message is clear: the achievement of maturity is the balance of the person. As for the setting, it is as crazy as the story, in the sense that so far (luckily) the transplants foreshadowed by the film have never happened. I don't know the novel from which the screenplay was based, but I found it absolutely logical to accompany a crazy story with an equally invented setting, in places that certainly exist with those names, but have never been as they are seen in the film. I also understand the reasons for the more critical opinions than mine on the film, I fully agree with the more than positive opinion on Emma Stone's interpretation, but in conclusion I must say that this film not only entertained them for its logical madness, but that it was probably very different it couldn't be done.
