I need a topic about comic books for a research paper I am writing. However, I am NOT writing a history about the comics, I am writing a persuasive topic about the comic books. Though I am not sure what about comics I should be writing about in my research paper. Any suggestions?

I am a young adult who has not read comic books since I was a little kid, but I am going to the comic book convention in Chicago tomorrow and I was wondering if anyone had any suggestions about titles I should look for that would help me get interested in reading comics again.
