According to Deadline, "I will state here that Flash is undoubtedly one of the finest superhero movies ever created."
He also stated that the narrative of the film "resets everything" for the franchise.
On the prospects of The Fantastic Beasts star engagement in DCEU future, the co-head of the franchise, Peter Safran, stated, "Ezra is absolutely devoted to their recuperation. We are completely behind them on their current path.
We will all figure out what the best road ahead is when the moment is appropriate and they are ready to have that talk."
"But just now," he said, "they are entirely focused on their recuperation. And, based on our conversations with them over the previous few months, it appears like they are making tremendous progress."
Before the film's completion, its primary star, Ezra Miller, made headlines for questionable behaviour, including unpredictable social media outbursts, arrests, and court appearances.
Miller apologised in August for their odd behaviour, indicating that they would seek treatment for mental health difficulties.
Meanwhile, The Flash hits theatres on June 16.
