Day 03 - A comic that is underrated.
So many, the Cass and Steph Batgirl series, Booster Golds' two series, and many more. I'm going to split this between an old series and a new one.
Spider-Girl (with Mayday Parker) was so good and multi-layered. It had so many interesting characters and ongoing storylines. It was a legacy comic done right that was always upbeat. Currently I think Red Hood and the Outlaws is greatly underrated. Many judge it based on the first issue when there's so much more to it than it's given credit for. It's a story about these hurt characters that help each other grow. It explores more genres than the usual Gotham crowd does.
