The title of this video is misleading. The titular TV’s Five Cardinal Sins aren’t sins committed by the well-known writer-producer of Lost, The Leftovers, and the upcoming (yay!) TV version of The Watchmen. Rather, these are the sins that Lindelof has identified and clearly despises.
In other words, it’s safe for Lindelof lovers to watch this as well as informative as hell for all of us struggling to replace him at the top of the showrunner pecking order. Enjoy.
