Does reading comic books help you improve your reading?

No. Because comics can distract you with pictures and can addict you to watch movies or play games.

Yes. Unlike classic literature, you will almost certainly have some interest in the plot and characterization within a comic. You will also encounter unfamiliar Words which are given context clues by the depicted action and the response of the characters. Like Video Games, comics tend to be surreal and superficial, but they can lead to an interest in more serious books, such as detective stories, Science Fiction, or mysteries. Unlike video games and watching TV, reading comics can be a painless way to expand your knowledge of the written Word.
