I'M OBSESSED!!

I powered through this and am so sad I don't have the remaining volumes with me right now! I need them asap!

I have seen the 2010 movie and enjoyed it, but never thought to read the comics it was based on, well now I want to read all the volumes. The humor is perfect and the characters just make the story, as many of you know I am very character orientated so having such an amazing group of characters in one story has gotten me obsessed.
I need to read the rest of them, I want them now!
