A dramatic monologue must be powered by an emotional release, conflated with an intense need.
When writers find the source of their rage, whether it be their interfering sister or global warming, or a no good boyfriend or their own self-hatred, along with their need to persuade us to feel the same rage, their monologues are perfect. Over writing, or self-consciously literary writing, which often gets in the way of good dramatic writing, is no where to be found. The acceleration, the rhythm and the length are always, if they have listened to instructions carefully, perfect.
Rage is empowering, especially if it is expressed with words, which is a measure of control, and it is an emotion all human beings share.
I was bowled over by the power of these white hot rage rants.
