Considering how important the graphic style in Tintin comics is, does the change of aesthetics in the Spielberg adaptation affect in a negative way the audience’s experience?
"affect in a negative way" is usually shortened to "negatively affect", and as a result longer version sounds odd, even though it's grammatically correct.
"...Spielberg adaptation negatively affect the audience’s experience?"
(alt: ...adaptation affect the audience's experience in a negative way?)
We start with a description of Hergé’s art style, based on his usage of caricature and its two formal mechanisms (simplification and deformation).
Good.
A very simplified art style with a medium-low degree of deformation in characters, but almost inexistent in backgrounds and objects, is very particular of Herge’s style.
inexistent --> nonexistent. Also the structure "inexistent in" is confusing - Are you trying to convey that he rarely has backgrounds and objects, or that those don't contain the same "simplified art style..." that the characters have? Regarding your highlighted area, "...is very characteristic of Herge's style." is probably what you're looking for. You could also use
distinctive if you want to emphasize that this style is rare and easy to identify.
I'd be strongly tempted to reverse the sentence structure, however:
"Herge's style is distinctive, defined by a very simplified art style with a medium-low degree of deformation in characters, but almost nonexistant backgrounds and objects." -- Note that this slightly changes the meaning of the sentence, so might not fit your needs.
As Hergé himself admits, his style, which is highly influential in the franco-begian “ligne claire” stylistic canon, is completely focused on facilitating the process of reading visual narrative for children and pre-teens.
Good.
While it’s simplification would make Herge’s style to be highly iconic, the careful and rigorous approach by his collaborators in finding and reproducing real references for the objects and backgrounds in his comics makes Tintin a realistic comic book, or, at least, a book that (as we may see today with the work of authors like Joe Sacco) illustrates the real world of its time.
it's --> its ("it's" always means "it is", it's the odd duck out in terms of possessive pronouns)
Reproducing is fine here, but if you're looking for a different word/meaning, give us a bit more info one what you want that word to convey.
It’s images are precieved and decodified by the young readers as real.
It's --> Its
Even with the visual realism intended, which is achieved with magnificent textural work, hyper realistic backgrounds and the usage of motion capture to give movement to the characters, Spielberg’s film doesn’t achieve the same effect as the comics.
Good.
The Adventures of Tintin: The Secret of the Unicorn, keeps a high level of deformation in it’s characters, very similar to the level used by Hergé himself, but disregarding any of his attepts at simplification.
disregarding --> disregards
You could also use "discards". Disregards means the movie ignores his simplifications, in a passive manner, almost by accident. Discards means the movie actively threw those simplifications away, not necessarily malicious, but it was by choice, not accidental or thoughtless.
Instead, the pursued effect is to show how the characters from a Tintin book would look in the real world, almost like in “untooned” art.
I'd go with "desired" rather than "pursued." It's not wrong, but it's an odd usage. You might also consider "attempted."
The achieved effect, though, is a very realistic reproduction, but not realistic enough as a human being to avoid falling straight into the Uncanny Valley.
The "as a human being" feels out of place. It introduces a subjective "human being" into the piece that wasn't introduced earlier, and forces the reader to make assumptions about this new character who is evaluating the work. If you want to keep this whole, you should consider replacing the "human being" with something referencing the audience, intended audience, etc.
You might also consider:
"The achieved effect, though, is a very realistic reproduction, but not realistic enough to climb out of the Uncanny Valley." or further: "The achieved effect, though a very realistic reproduction, is not realistic enough to avoid the Uncanny Valley." You could also replace "avoid" with "bridge" if you like the "valley" part of the metaphor and want to extend it.
It removes the human, keeps your overall sentence structure, and tells the reader that the movie fails to keep clear of the uncanny valley. It also implies that the movie actively tried to avoid this trap, but failed. Hopefully that fits your needs.
Even if they look objectively more real, the hyper realistic renderings of these characters are perceived as grotesque deformations, an effect that affects negatively the audience’s experience.
"...an effect that negatively affects the audience's experience." would flow a bit better.
