An Apple TV+ show shares many similarities with Lost but already avoids one big mistake that weighed down the classic ABC mystery series. Airing from 2004 to 2010, Lost is still one of the most memorable TV shows from the mid-aughts, known for its immersive serialized storytelling and expansive world-building. In its runtime of 121 episodes, the show adopted many intriguing narrative devices and took many risks to cement itself as one of the most innovative and important television shows of the 21st century.
