Honestly the previews made zero mention that the original writer and director of the original Mad Max trilogy was doing the movie. The previews made it look like another hack director doing another tired remake of an old classic. All they had to do was tell us it was a heralded return of the original series creator within the trailer. If I didn't do my own research, read up on it and read some reviews, I would have had no idea.
Studio failure to properly market their movie IMO.
Mad Max movies are really hard to market tho. The trailers and teasers were amazing! They did a ton of buzz, but the movie isn't for everyone. They are kind of artsy Action movies and that doesn't appeal to the same mass market as most action movies do. And Tom Hardy isn't exactly Mel Gibson or a bonafide boxoffice star like Leo is.
