12. Six Feet Under (2001-2005)
Every episode of Six Feet Under opens with someone dying, sometimes tragic, sometimes absurd, always sudden. That structure could have gotten old fast, but it kept forcing the Fisher family back into the same room to deal with what death actually does to the living. Nate and David's fights felt like real sibling stuff, not scripted drama, and Claire's whole arc growing up on screen still hits different on a rewatch. Then there's the finale, which jumps decades ahead to show how everyone eventually dies, and somehow it plays like comfort instead of dread. | © HBO
