I am going to agree with you. Really, Harley Quinn was over played. The other characters where down played, given very little to know back story, and Will Smiths character Deadshot was just his character from Badboys all over again. This was a concept that had SO much potential to be such a great story and surpass the actual heroes that these villains faced. This movie was nothing more than a prelude to the anticipated Harley Quinn movie in which we could possibly see Margot in the Cartoon Harley costume. Still, Harley is only a secondary character who is a sidekick to a much bigger fish that is quite a horrid creature. Wish they would do a movie about him with how he really treats Harley.
