The Avengers is one of the most successful movies to date, even outside of the comic book movie genre, but there will always be dissenters and even after going over pretty well with critics and becoming the 3rd highest grossing film of all time, some critics were highly critical of the film.
Samuel Jackson himself lost his temper with a New York Times Reviewer who he felt was overly critical of the film. Jackson took to Twitter and suggested that the critic should look for a new job.
Joss Whedon is a little more cool-headed than Jackson, but still felt that the negative reviews were unfair, in the sense that most of them were criticisms of the genre rather than the film:
“I went into a bubble when the film came out,” says Whedon, “but I do know that Sam Jackson got pretty huffy. I don’t think a flame war is going to help anybody. People are allowed to not like the film.”
“But I do get annoyed when somebody really hasn’t done their homework. A lot of reporting in the negative reviews… was more like they were reviewing the [superhero] genre than the movie itself.
