It sounds like you're referring to the anime Banana Fish — specifically a version with subtitles ("legendado" means subtitled in Portuguese).

If you share the article's title or source, I can give you a more precise summary or analysis. Otherwise, are you looking for legal streaming options with Portuguese subtitles?

The article you saw likely discusses the series' dark themes (based on the 1985 manga by Akimi Yoshida), its cult following, or where to watch it legally with subtitles. Banana Fish is known for its intense story set in New York, dealing with gangs, conspiracy, and the relationship between Ash Lynx and Eiji Okumura.
