It's all about the Suicide Squad
Amanda Waller sends the Suicide Squad to break into Arkham Asylum. Waller is as cold blooded as ever making her a great character. The movie is really all about The Squad more than Batman. Of course, as you would expect putting a bunch of bad guys together never works out and there’s a grand finale when Arkham goes wild. The ending stands out as well.
