More truth hidden in plain sight, even if it's a bad movie! In Green Lantern the enemy known as 'Parallax' is that of a recurring theme we keep seeing. The Archons. This being Parallax was benevolent in it's origins. It is that of a being that began as an immortal, who sought to harness the power of fear to conquer it. Only to be consumed by that fear and turned into the very essence of fear itself. Destroying and conquering worlds feeding off that fear. Sound familiar?
"Our fear of death is what gives Dormammu life"
Many iterations of this theme is seen across different genres of movies, all with slightly different tones. Perhaps showing the nuances between different Archon paradigms.
