I was never much of a DC comics guy except for the big ones; Superman, Batman, Wonder Woman, Justice League, etc. But yes, deep cuts is the future of the comic book movie. This is how WB/DC is trying to replicate what Marvel did with
Guardians of the Galaxy which is take an obscure deep cut and make it wildly popular.
The draw here of course is Margot Robbie as Harley Quinn and Leto's Joker. (I *think* I went on the record as saying the tattoos didn't bother me.) Harley Quinn was created for the 90s Batman cartoon and became insanely popular as a "sidekick" to the Joker. It's a real Richard Burton/Liz Taylor/
Who's Afraid of Virginia Woolf? type of relationship.
And Robbie is ridiculously attractive.
