It was commonly stated by many that Greg Berlanti would be a better choice to run the cinematic universe due to his DC shows being considerably lighter. Then the trailer for this series dropped and he was hit with the same accusations of making heroes needlessly darker and grittier. It's arguably even more damning for Berlanti as Zack Snyder never resorted to having heroes say "fuck" for cheap shock value and his films were visually amazing in contrast to the othercomplaints against this series.
Speaking of the infamous "Fuck Batman", it was frequently cited as an example of the series being another humourless Darker and Edgier reboot. The full scene, though still being brutally violent, actually starts with a joke of Robin appearing and all the mooks immediately looking up in search of Batman, with Robin giving an exasperated "Fuck Batman" after taking them all down single-handed.
And then the "even Snyder never resorted to heroes saying fuck" criticism becomes even more hilarious when Snyder revealed that Batman would drop an F-bomb in the Snyder Cut, if it wasn't already noted that he had already had Batman say "shit" in Batman v Superman: Dawn of Justice.
The series exists on streaming services to begin with because TNT passed on the series. Then, in July 2021, the channel started airing the show anyway.
