I must agree. Black Panther was a good, B+ film, but it was not some revelation in the art of filmmaking, the superhero genre, or Marvel movies in general. Despite many an entertainment business mouthpiece being typically offensive by almost implying that this superhero movie is akin to some next phase of the Civil Rights Movement, the film made its comments, but as I observed in my review, its been spun by both the Left and Right to argue for or against agendas of their own making. Unfortunately, if the film won Best Picture, the doors of this ideologue war would be blown off for more ranting, which serves no purpose and advances no cause.
Other fantasy films that received Best Picture nominations actually made a major shift in the business and/or popular culture, such as Jaws (1975), the original Star Wars (1977) or altered the perception of how great a fantasy movie coulf be as in the case of Best Picture winner The Lord of the Rings: The Return of the King (2003), but Black Panther is not that kind of film. No current superhero film earned that distinction.
