I think graphic novels are definitely worth your reading time. Why should it not? Its only difference from your regular books is that it has illustrations. Both a book with only written words and a graphic novel tell a story. And, I think the ability of conveying a story to the reader is the important question. I actually admire graphic novels because I can only imagine the amount of work inputted to create a story. A person needs to create the story while another person creates the dialog. Some people sketch the artwork, other people create the line art and a different person colors the panels. If I could be honest, I think it is a different type of art form that I truly respect. Not only can my mind feast on the story written in the dialogs, my eyes can also enjoy from the beautiful artwork created by the artists. Don't get me wrong, I also salute those who writes novels. Putting a world with just using words is also hard work.
