The reason I love the comic book medium is because it's human instinct to tell stories in pictures. Pictures have been around longer than the written word, and some of the earliest languages were carved in imagery instead of sound or text. I also like comics because there is actually more to read in a comic than a book. In a comic you obviously read the words, but you read the words in relationship to an image. You then have to read the visual relationship between panels. Because the words and images are separate in a comic an artist has a lot more freedom to experiment with storytelling since the words can say something that the image can't and vice versa.
