When did Lost jump the shark? 🦈

Season 3, Episode 22

Lost is often considered to have 'jumped the shark' during its third season finale, 'Through the Looking Glass.' The episode introduced a flash-forward narrative technique, which, while innovative, marked a significant shift in storytelling style. This change confused many viewers and signaled the beginning of increasingly complex and convoluted plotlines that some felt detracted from the show's original appeal.
