I just finished "Serial", hosted by investigative reporter Sarah Koenig.
It was about a kid, Adnan Sayed, who was tried and convicted of murdering his ex-girlfriend back in 1999 when he was 17. He's maintained his innocence, and there were a LOT of unanswered questions in the case. His attorney, who has since passed away, did a pretty piss-poor job in many facets of his defense.
It was actually pretty riveting, and I didn't want it to end.
It was really, really good.
