These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Batgirl 2011
Alternative Character Interpretation: Regarding Barbara, and whether she's an intelligent and strong young woman regaining her confidence to overcome trauma or whether she's massively overconfident and not nearly as strong or clever as she thinks she is, instead blundering into situations she's not nearly equipped or prepared to handle.
Some thought having Barbara becoming Batgirl was great, others... didn't.
There were people pissed at the reason Barbara no longer handicapped being a "miracle", though later in the series it is addressed fully and referred to as a neural implant, which is based on real technology that's currently being tested.
Plus, the first villain Batgirl faces is a deranged man named "Mirror" whose M.O. is to kill people who were saved from death by chance, thus undoing the "miracle". He might have been a Take That at the fans who thought Barbara should have stayed handicapped, though Word of God is that much of what's been perceived as meta-commentary actually isn't.
Also, many people (including DC editors, before the reboot, anyway) thought she became a much more interesting character as Oracle than as Batgirl.
What an Idiot: Barbara Gordon isn't nearly as smart as she was as Oracle due to being several years younger. In issue 10, a group of security guards who are obviously up to no good threaten to call the police if she doesn't leave the property immediately while she is busy helping out a man who got caught in bear trap. Most of the bats would play along and pretend to leave while dropping a tracker on one of the guards or hiding out in the shadows. Barbara does none of those things while acknowledging that the guards were acting suspiciously.
