"There was no fucking message of the film though. It's a fucking novelty film. "
"It was a fucking romantic comedy. It was shallow as fuck. If you think The Artist was "deep" I pity you. "
So, you say the movie didn't have a subject because the STORY was more in line with a romantic comedy, therefore, there is no subject because Romantic Comedies NEVER EVER have a subject.
The movie is about the evolution of cinema, it is presented as a Black and White Silent Movie, it uses it's elements to show the tribulations of George Valentin in his struggle to keep being relevant despite shunning the new elements of cinema that, he feels, are a gimmick.
In the end he recovers, not by just copying what has become the norm, but by adapting his perceived lacking skills, he thinks people won't want to listen to him, by foraging in a new kind of movie, Musicals. As he accepts new Ideas, his world (the movie) changes.
The lack of sound and Color are used very carefully thru the movie, like the dream sequence where everyone and everything emits sound, except Valentin himself.
You see, the movie is about the subject, the movie uses it's elements to covney this subject in a modern way, using elements of Silent movies. Even the acting is made in a way that mimics over the top silent movie performances. And the key word here being "Mimics". The movie is not being a direct Silent Film. If you think it's a generic silent film, it's because you have never actually watched a silent movie.
The movie could have been made in a traditional way, with the characters talking, subtle acting and color, but it would have been a different movie, a different experience.
It's nto the DEEPEST MOVIE EVER! I neevr said it was LOL SO DEEP. Is an interesting movie that uses it's elements in an intelligent way, not because is a silent film. Which it is not.
A story is not a subject, a Plot Synopsis is not a critique, a genre is not a limit.
