However, the film has so far been heavily criticized by reviewers; only 27 percent of critics have given "Suicide Squad" a positive assessment, according to the review aggregator Rotten Tomatoes.
Fans of the movie reacted negatively to the bad press and complained about critics on social media. One fan, Abdullah Coldwater, started an online petition calling for Rotten Tomatoes to be shut down, but later changed the petition to one advising people not to listen to film criticism.
"You may enjoy a movie regardless what the critics say about it," he said on the petition's page on Change.org. "We must get the people to know that the criticism is not the measure of the quality of movies, it's just the opinions of the critics."
More than 19,000 people have signed the petition so far.
The reviews aren't likely to directly affect the box office of "Suicide Squad", according to Daniel Loría, vice president of content strategy and editorial director at publishing firm BoxOffice Media, as the fans who reacted angrily will see it regardless of critics.
"Film criticism is most impactful at the box office when there's an element of discovery to it: Awards contenders, foreign films, or independent movies for example," he told CNBC via email.
"Critical reception is fairly limited when it comes to a franchise this recognizable; people who enjoy the characters and are interested in the material will likely turn out."
