“I hate to be hysterical about it, but The Leftovers is absolutely clowning the rest of television in this quantum leap of a second season. It’s doing monster-truck wheelies over the competition. There’s been a lot of amazing television in 2015, but with every new episode of The Leftovers comes the very real possibility of seeing a “top 10 episodes” list violently upended.”

This is spot on. The Leftovers was just OK the first season. It has reinvented itself into something otherworldly and mesmerizing this season. It’s a must-watch show. Even the opening credits are phenomenal.
