When was the last time you really fell in love with a TV show?

We all wish that "the one" would come along every season, but let's face it. You probably won't fall deeply in love with a new TV series every year — or even every decade. There are only a few that are ultra-special. What was your most recent experience of true TV love?

Please include a description of the show, and some links, video and pictures, so we can all share your feels.
