The cult hit returns with a two-hour episode that, even by Lost standards, is jackalope-crazy—and, for fans, unmissable. The concept of coming unmoored in time, introduced in Season 4, gets ramped up to a degree that's exhausting. Please make it stop! Then Hour 2 ends with an urgent warning of doom that, as apocalypses go, feels a bit over the top. What keeps Lost anchored are strong scenes of concrete human connection. When Hurley (Jorge Garcia) explains his adventures to his mother, she grabs his hand: "I don't understand you. But I believe you." You may find yourself unexpectedly verklempt.
