Constructed flawlessly. Humanized and focused on the victims individually bridging empathy to the audience whilst switching to provide scientific explanations about how the catastrophe happened. The layering was perfect and the sequence of information episode-to-episode made me glued to the screen. I sat there and watched it all in one sitting, no bathroom breaks or nothing. Brought me to tears. Favorite doc ever (and im an avid watcher of true-crime and information filled scandal docs). Recommend whole-heartedly.
