I think the first serial is going to be tough to beat, because most of life doesn't have the narrative of a story, and Adnan's almost did.
Shittown starts off sounding like it's going to have those narrative beats we yearn for in storytelling, but just doesn't.
I love how the story constantly pivots for the first 5 episodes as we learn that no one is totally innocent, no one is totally shady, and that life is a set of circumstances with no single answer for anyone. In general I think we desire answers and clear points of connection in narrative in a way that has become dangerous, because we expect that from non-fictional sources, and we see that constant hunt for handed out meaning and intersecting points of cause and effect in everything, including our news. Don't get me wrong, narrative fiction is my jam, and it definitely fulfills a need, but to expect it from real life is folly. I think a huge portion of our society now relies on narrative to understand the world and that is extremely dangerous... but that's a different discussion.
I thought this was touching and brilliant and it did seem to slow down just a bit by the end, but the mercury poisoning thing was fascinating and seemed to make sense of the chaos before it. People self mythologize all the time, and John may have been the biggest out there, leaving more questions than answers and digging a trench to fill up with gossip, when the reality was he was poisoned, and all of his genius couldn't save him from that.
