The Flash is referred as the finest superhero picture ever by DC Studios co-head James Gunn

Ezra Miller’s The Flash will be screened for theater owners at CinemaCon on April 25, six weeks before the movie is scheduled to debut on June 16. This is a vote of confidence in the movie.
The Flash has lately been hailed as “one of the greatest superhero movies ever created,” according to James Gunn, co-head of DC Studios.
The Flash, a highly anticipated superhero movie based on the same-named DC Comics character, stars Ezra Miller as the title role. This is Miller’s seventh outing as The Flash in a major motion picture, following appearances in Batman v Superman: Dawn of Justice, Suicide Squad, Justice League, and Peacemaker series on HBO Max.
David Leslie Johnson-McGoldrick, who also co-wrote the two Aquaman movies with Jason Momoa for Warner Bros. Discovery, has already written the script for The Flash’s potential sequel. Yet, James Gunn and Peter Safran neglected to bring up the Flash sequel during their DC Universe presentation.
The Flash is based on the Flashpoint comic book story, which followed Barry Allen as he traveled through a modified DC Universe. It was directed by Andy Muschietti, with a screenplay by Christina Hodson. Geoff Johns and Andy Kuber’s creation, Flashpoint, radically upended the DC Comics universe’s established order and prepared the ground for the launch of the New 52 series.
Along with Michael Keaton and Ben Affleck playing two different versions of Batman, The Flash also stars Ezra Miller, Ron Livingston as Henry Allen, Maribel Verd as Nora Allen, Kiersey Clemons as Iris West, Michael Shannon as General Zod, Antje Traue as Faora-Ul, and Sasha Calle as Supergirl. Saoirse-Monica Jackson, Rudy Mancuso, and Luke Brandon Field all play undefined parts.
