The journal comic can be a limited genre ... that is if you choose it to be. You see, many people confuse a journal comic with a diary comic. If you do a strict diary comic of, "this is what happened to me today" then it will become boring if you think your life is boring.Although that could tell you about your personal life and psychology. If you think your life is boring, then doing something about it. Your life is in your hands. What do you want to read in your comic, then make it happen. But that is too much psychobabble for this conversation.
The journal comic can be more than what happened to you that day. Nobody cares what you ate for lunch. This is an open forum to say whatever you want to say about the world. You have done some political comics within your journal that is a good point of this. However it is more than just editorial comment. It is more about finding beauty in the life around you and capturing it. Also it is not only reporting the world, but dramatizing it as well. You draw yourself as a bear ... we know that this is not a strict interpretation.
Here are some samples from one of my favorite journal comics (via reidsrow
Everybody blows their noses and has their ears pop at least once in their life's. So what? Matt found something that readers can connect to and dramatized it. It took that intangible feeling and made it into a series of images.
Here is another example of taking a intangible feeling and putting it on paper. However in this one it dramatized an emotional feeling. What this is also is an examples is breaking down the barriers between the reader and artist. Not about invading privacy, but bringing an intimacy into the comic.
On the other hand, you can take a tangible object and meaningless occurrence, but add beauty and feeling into it. This is a comic about nothing at all. Yet it is one of the most beautiful comics I have seen.
One of my favorites. All he did that day was clean the kitty litter, but yet Matt made it into an epic tale. Drama and comedy! Something is only menial and boring if that is what you make out of it.
You do not have to make your comic like Matt's, but it is just to demonstrate a way to go with it. Do not stop draw journal comics because you think they are boring. Continue making journal comics and MAKE them interesting. You are an artist and creator, the choice is yours.
