AMC’s The Killing is offering one of the best second-screen experiences I’ve seen for a scripted show. We’ve been watching The Killing Story Sync on AMC.com for every episode of Season 3. The features on Story Sync add additional depth to the show, with images of important documents in the show and live polls about where the show’s plot should go. The best parts of the Story Sync have been its close-up images of evidence in the ongoing case of Season 3, as well as all the documentation for the imprisoned Ray Seward. I would love one of these type of Story Syncs for Mad Men next season.
