The problem for me isn't the character, it's the writing. She's a damn good character. The real problem is, Cecil Castellucci. She's a bad writer. A comic book character is only as good as their writer. She doesn't understand Barbara and hasn't been able to find her voice. Which is probably why the character's actions and words have been so OOC. You can compare the way, Castellucci writes Bab's to the way others who understand the character do. At the end of the day, I'm not sad this volume of Batgirl is ending because at least that means Castellucci will no longer be writing Babs. She writes a very poor version of the character. The irony of all of this is they had a good writer, they treated her badly and this writer is the replacement.

Slow moving plot. Literally the only movement comes from pink hair girl's exposition. We learn what the monster thing is, it's origin, annnd it's (apparent) motive for coming after Barbara. Needless to say, that is way too much to reveal in chit-chat from some random OC. Sans Cela's convenient narrative, the plot has no meaningful movement

Nothing much happens. (Extra point for slight intrigue about some of the breadcrumbs the comic does drop.)
