My only probelm with Suicide Squad was mainly the end, which I felt was too much like Ghostbusters (I wasn't the only one). A different villain might have been a better choice.
That said, Suicide Squad still did well at the box office, raking in $745.6 million, with a sequel and a Margot Robbie Harley Quinn Gotham City Sirens movie in the works.
CinemaSins offers on Suicide Squad: "Well, here's an absolute travesty of a movie, from start to finish. Suicide Squad has so many sins, I considered quitting. This movie is just... bad. And here are its sins."
