At some point, nearly every fan of comic book movies held a grudge against Martin Scorsese when he expressed his opinion, that comic book movies didn't qualify as true cinema.
However, despite the controversy stirred by his comment, it's hard to deny the fact that this 80-year-old filmmaker is a true master of his craft. With 26 films in his repertoire, Scorsese's popularity largely results from his expertise in creating movies, primarily focused on the crime genre, basically gangster stories, and his works tend to lean toward in-depth character studies.
