In an interview with The Independent, Perlman said, “F**k you and your self-importance and this self-perpetuating need to say everything bad about something just so that you can get some attention for something that you had no idea about creating.

He added, “It’s corrupt. And it’s sick. And it’s twisted.”

The film currently has a 55 per cent positive score on Rotten Tomatoes, with some more critical reviewers calling the movie “mean-spirited and smug” and “toothless.”

Perlman went on to say that he understands “that it’s part of how the internet has almost killed journalism. And now journalism is trying to do everything they can to co-opt and maintain their importance.”

Journalist David Sirota, who helped conceive the story with McKay also struck back at critics on Twitter.

Speaking with IndieWire, McKay clarified is comments, saying, “It’s important to have debate and passionate critics. We’re living at a time like no other and stories are part of it. People should be hating them, loving them, going back and forth. We welcome the negative reviews. I actually think it’s really good, that people should be fighting and passionate about it.”
