I am part way through the Documentary but I had already listened to the Wondery Podcast, which I thought did a great job of reviewing the case too:
Much like @New Zealands #1 Colts Fan it wasn't as big news in the UK as it was Stateside and so there was a lot I didn't know about it and so, coming in cold, it really was shocking in terms of the actions of someone who, from the outside, looked to have it all.
I don't think you can discount the CTE side of it, as there does seem to be a graduation from a happy high schooler who was popular, funny and well-liked to an aggressive paranoid murderer with little consideration for life.
However, we will obviously never really know the full story.
Thanks for the invite but I have a new job that is presently monopolising my time! Not only would I struggle for time in making selections but would want to be able to do a bit of research as well.
Good luck to the rest of you though!
