Certainly one of Scorsese's most underrated films; Even though it absorbs the main aspects of period novels/dramas, it is interesting to see how it is completely related to the themes worked on by Martin Scorsese in his Gangster films, while in these films (I would mainly mention "Goodfellas"), the characters carry a whole "brand" of mafia and money, but they have to leave their individual desires aside, in favor of the institution's confidentiality, in "The Age of Innocence", these characters not only have the "brand", but also seem to have individual freedom (the United States, as this great synonym of freedom), but which is never realized, due to a series of social rules in this society.
In theory, they are very antagonistic institutions, but in practice they carry the same problems of loss of individuality of individuals, who, in this case even more so, have to live their lives of regrets and insecurities, in a totally regulated and robotic way, where this "freedom " is just a pretty facade for a prison of rules and mistrust.
The scenes between Daniel Day-Lewis and Michelle Pfeiffer absorb more and more as time passes, an aspect of a dream (the American dream), as it is unattainable, it is unthinkable, their desires become more and more distant; I think the scene where Michelle Pfeiffer's character is on the seashore looking at a lighthouse is the central scene of the film in that sense.
These characters start to question this world (the political individual who cannot win against this institutionalizing collective), when they find themselves trapped in their own dreams, especially the female characters, just like in Scorsese's crime films, here the strong sexist character in the functioning of this institution. Great Scorsese film, I highly recommend it, now I look forward to watching Killers of the Flower Moon soon 🙌
