Blacksad is a must read. I know IDW has picked up on Robert Bloch's stories... I read the Your's Truly Jack the Ripper series but it wasn't so great... so I don't know what the rest of IDW adaptations will be like =/
I picked up an issue #1 of the All Nighter really having no expectations for it but after reading it, i'm hooked. About a group of misfitted teens who are planning a robbery. It's dark and dry. I would recommend it for those who liked the Runaways, and Morning Glories.
