Apparently, DC will release a series of tie-in comics to the upcoming Birds of Prey movie.
I'm both skeptical and very interested.
Skeptical, because I'm afraid it'll be used to handwave some difficul plot points (like, why is Harley not with the Joker, who came to "rescue" her at the end of Suicide Squad) and I would hate to have to read a comics to understand a movie, when the two mediums are so vastly different (and I don't like the idea of being forced to pursue special comics/series to understand a movie).
But I'm also very interested, because it seems that DC truly is banking hard on this movie to succeed, and is willing to pursue some real push for it to do so, probably thanks to the aura of Harley Quinn, and if it means that Black Canary, Huntress and Cassandra Cain gets more of a spotlight for audiences, I think it could be great for the future - especially if the powers that be realize that this movie is a perfect way to introduce new characters and groom Cass as a future heroine able to have her own movie.
Now, we'll have to see the quality of said comics, of course.
