Others I've watched recently.
Paradise Lost series - one of the best things I've ever watched, as mentioned countless times on this thread.
The Staircase - Unsure of the exact name, two part on author Michael Peterson's trial in the death of his wife.
The Trials of Darryl Hunt
Teen Murder : Micaela Costanzo - 16 year old murdered in a small town in Nevada
Witch Hunt - About a number of families in a town in California jailed for child molestation. Crazy stuff.
