Nekron is honestly an underrated DC villain and I feel like if we eventually get Green Lantern back on the big screen than Nekron can really be built up as an almost inevitable and unstoppable threat since he is technically the end of everything, the God of Death that will always exist as long as life exists, sort of like unstoppable force of nature like Death itself. Id love to see a live action adaptation of Blackest Night event in the long term future some day, sort of like Green Lanterns own version of Infinity War & Endgame that affects everyone in the DCU.
