Christopher Nolan's new biopic, starring Cillian Murphy as physicist J Robert Oppenheimer who helped develop the first nuclear weapons, has been a box office hit and is already tipped for Oscars success.
But social media star and boxer Paul, 28, confessed on his podcast ImPaulsive: “I walked out of Oppenheimer.
“I didn’t know what they were trying [to do]. 'What are you doing?’ Everyone’s just talking. It’s just an hour and a half, 90 minutes, of talking, just talking, talking.”
“It’s all exposition. Nothing happened.”

The YouTuber is not the first person to go against the critics and confess they did not enjoy the film.
Billionaire Elon Musk, who last year took over social media platform X [formerly Twitter] also branded the film dull.
Musk, 52, shared a picture of himself scrolling through his phone during a screening of the movie, captioned: "This Oppenheimer movie is way too long."
He has also responded to complaints from some audiences who said they struggled to hear the dialogue in parts of the film.
Nolan told Insider: "I like to use the performance that was given in the moment rather than the actor re-voice it later.
"Which is an artistic choice that some people disagree with, and that's their right."
The film is three hours in length, which some critics and cinema goers have complained is too long.
Oppenheimer is not the first film to prompt audiences to walk out of screenings before the end.
