Batgirl, Volume 1: Batgirl of Burnside

This comic made some really questionable story decisions, especially early on. At times it was ridiculous throughout. Despite that, there are some really fun characters in this, and the twist at the end made a lot of the stranger ideas make sense. I recommend if you want some shameless fun to try it out, but give it until the end before making a decision on it.
I also just personally love the ongoing grad school thesis plotline, it gets me.
