I must admit, I didn’t read the original Rocket Raccoon miniseries because I didn’t like Mike Mignola’s art back then. It took a while for me to appreciate his work. I think it was when he did a fill-in job on Byrne’s Superman reboot that made me realize how good his artwork was.
As for Rocket himself, I liked his storyarc the best among his fellow Guardians of the Galaxy in the movie trilogy.
