I was curious about this because I really like the concept of the Joker. My brother knew it so he sent me the link.
It was very different than what I was expecting but it really got me curious about the New 52.I haven't really read enough to be knowledgeable about it. Before I saw this, I didn't think I would be.
One of the things I've always liked about the Batman Rogues Gallery was that they were only villains that could arguably be horror villains. This was the proof.
I was really intrigued by the portrayal of the Joker, because he really didn't seem like he was criminally insane to me. But rather he was a personification of evil. As subdued as the actor was, there was this sense of him guiding along Harley like a vampire would one of their victims.
It is, however, not for the faint of heart. It's the most violent version that I have ever seen. It's the perfect psychological thriller short.
