I enjoyed reading Maus as a comic. Although often throughout the book I found myself just reading the words and having to go back and look at the pictures. They added to the story, especially the mouse/pig aspect of people really helped differentiate who was of help and who was not. Adding pictures to the book also made it more interesting to read, things that would normally take lines upon lines of descriptive text to paint a picture were simply just pictured. A great example is when he is sneaking around to find food, you can see the darkness and danger involved without even reading a single word. When the author is describing the secret bunkers, one can truly understand how it was laid out because he simply drew it. If it was only text, it would have been very difficult to understand exactly how the bunker was made. There are however some drawbacks in making the comic. On some pages it was difficult to follow exactly where to go next. Sometimes I would accidentally skip over a scene and all of the sudden get very confused and have to go back. The comic also must have taken absolutely forever to draw, every scene is depicted with great detail, I could have never drawn something like that, given I cannot draw very well in the first place.
There are several parts of Maus that really would only work, or work best in comic form. One is the description of the bunkers as a mention earlier. Also, the dialog in a comic is much more real. I feel that if Maus had been just a book, I would have not had nearly the same understanding of the dialog. This is due to the fact the author can write the dialog however he chooses, in different font styles, in all CAPS, with weird punctuation, etc. It really helps you get a feel of what the characters are feeling. Another thing that would only work in comic form is the whole mouse idea. In the book the artist uses mice, to symbolize the Jews, and pigs to symbolize pretty much everyone else. During parts of the book the main character wheres a pig mask to show that he is disguised, which provides some light humor. The whole symbolism could not really be put into words, and it would have really taken away from the story.
Many books could potentially be turned into comics. I do not really have the creative talent that the author of Maus did, but I believe someone with his talent could turn nearly any book into a comic. Even Into the Wild could be turned into a comic strip about mice. I think that turning it into a comic strip would tell a totally different story, however if done right it could probably be a pretty decent comic strip.
