Suicide Squad is a curious film. It was by far one of the most ambitious titles in the DCEU when it released, as it focused on established villains without showing them (more-or-less) fighting the heroes that they are known to clash with. Despite it doing well financially, critics and fan noted a very uneven film, and the limited user of The Joker was harped on by many. The director of the film, David Ayer, has now been attached to a spinoff film featuring Harley Quinn, Catwoman, and Poison Ivy. Aka The Gotham City Sirens.
