Book of Judges

For OTA 104150 Mr. Mark House:  We were so impressed with your assistance that we requested your help on one last question our study group is thrashing out.  

We wondered whether the Book of Judges shares a common theme [things like ideas, structure, language, etc] with other Old Testament books and supposing that it does....then what are they (please be specific cause we really want to thoroughly understand this) and does that help us (the people who read Judges) understand the message of Judges?
