I just wish Harley and Joker relationship were like in this movie all times, but the nature and story of both characters won't ever allow it. At least i finally got Joker and Harley happy here
I wish it was more friendship-like and healthy, like in Lego Batman. They would be so powerful. But unfortunately like you said, the writers and stories will never let them be healthy. :(((
harely is just as twisted and evil as joker.. she's done some really fucked up things in the comics. don't be tricked into thinking she's an antihero just because of the injustice games..
