Is this reviewer ignorant of the tragedies of Euripides and Sophocles as well as Shakespeare? Where there is no on-stage antagonist? Or Wagner's Ring Cycle? Where the ultimate antagonists are the fates? Good grief, get an education.
This reviewer has seen the Ring Cycle, and has read all of Shakespeare and significant chunks of Euripides and Sophocles. Please rest assured that this reviewer's education is not to blame for any deficiencies in her work. What this reviewer was trying to convey about Heart of a Soldier is that it seemed allergic to the very idea of an antagonist, and that because of this aversion, the work lacked dramatic immediacy and credibility. You are right that I should have made this clearer.
Thank you for reading, and I appreciate your critique.
