The Book of Judges - Is There a Parallelism?

There's got to be some parallelisms going on. At the end of the book of judges, god doesn't forsake his people. They are in bondage twice as much as they are delivered. Samson only gives them 20 years of deliverance and rest. But samson is like the worst judge of all because he can't fulfil his vow. He cannot remember what God wants him to do till the end of his life. His eyes have been taken out of his eyes by this sincycle.
