Quite a start. The Joker gets caught quickly-by Batgirl. It's not long till Batman and Robin show up. They both realize something's wrong since Batman knows Barbara Gordon can't even stand and this Robin has never even seen her as Batgirl. That guarantees a good story seeing as it's only a few pages into it so far.
This was a good start to the "Zero Hour" saga and continued into a great Superman issue as well. It also has a brief cameo with the original Robin that developed in that month's issue of Robin. The only down side is even though he's on the cover, Nightwing doesn't appear in the story. He'd have added intrigue. I'd have loved to see how he and Batgirl reacted to each other. Other than that this was a great book and gave a great indication that things were on the way to being back to normal after nearly a year of the "Knight" sagas. more
