Poorly written and frenetically paced. The constant plot narration by Harley and flashbacks make this movie feel more like a game of tennis with a dated alt metal soundtrack. There are some visually awesome scenes, the police station comes to mind, and Margot Robbie shines at times as the kind of titular character, but the writing falls way short of doing her performance justice. There are also no character arcs to invest any sort of emotion into. I thought DC and Warner Bros would have learned their lesson after the Suicide Squad disaster, but they haven't. This isn't close to as bad a film, but it's in no way good.
