It's not like her new title is a total crap, but the Barbara that stars it doesn't look like the Barbara I know and came to love. She seems much younger, she's so reckless and doing so many stupid things. In issue #38 they tried to adress this question by making Barbara say, while she was arguing with Dinah, that she finally had a life and friends and she deserved it after everything she's been trough. Ok, but being reckless while wearing Batgirl's cape doesn't seem smart or understandable. Afterall, citizens don't know she's Barbara Gordon, so it makes no difference to her social life. So I agree with Dinah, she's acting like a child.
Anyway...I still think these plots would work better for Stargirl or any character of that kind. Especially because they're much more like teenagers than young adults.
There are others ways of making a comic book be fun, rather than just turn its main character into a new character :/
