I have no interest in seeing this movie. Batman, Joker and all of Gotham has been done to death.
I'm also not a fan of the character at all. I've always thought that Joker is a pretty lame villain when you think about it. He's a psycho who kills people for no reason. Usually, those are called one-dimensional villains. Sure, I've heard that in this movie they changed that and gave him reasons but all of that still doesn't sound like a lot of fun.
Right now, when it comes to DC and their movies, I'm more interested in seeing Aquaman for the second time.
In Aquaman, he beats up the bad guys. Like it should be in a comic book movie.
