I'm not entirely sure how she came to be among the living again, but it's a comic, so it's only a matter of time until dead characters are resurrected. Anyway, she ended up on the mortal plane again, and we're so much better off for it.
1. Her inner monologue uses capslock when the sitution is socially awkward enough to call for it. And she's such a socially awkward penguin that you can't help but love her.
2. Unlike the vast majority of the Bat-family, Steph does not feel the need to be a complete jackass. Compare Dick's reaction to meeting Detective St. Nick to the message Steph leaves him after their first encounter:
3. Steph's the only person who can make Damien bearable. Sometimes that means freezing him in a block of ice, but in the most recent issue, we saw them actually make a pretty good team when Dick tried to sideline them.
4. Oracle is her mentor, which means there's lots and lots of grumpy Oracle. Grumpy Oracle is the best thing ever. Seriously, I wish Babs was my curmudgeony aunt.
And with Birds of Prey returning as an ongoing series, there will be even more Babs!
5. Batgirl is full of Buffy-style humor, and pulls it off way better than the current ongoing Buffy series. And with the comparative serious business of Dollhouse, my life has sorely been lacking in this department.
6. Steph avoids being another broody member of the Bat-family, even though she has ample reason for being Ms. Doom-and-Gloom. She was brutally murdered by Black Mask, for starters. Everyone except Babs thinks she's going to get herself killed again, and Babs only changed her mind recently. Despite all of this, Steph manages to crack jokes and make bad puns when she's getting her butt kicked.
And although she's no longer Robin, Steph is filling the usual Robin role of being a source of light for Gotham. Batman works through fear and intimidation, and while Dick is considerably less moody than Bruce, he's followed Bruce's Batman scary persona. And Damien isn't exactly a little bundle of joy as Robin. Babs described him as "a murderous little twit." Steph, on the other hand, has a different understanding of how superheroing should work:
And that's why you all should be reading Batgirl.
