The TV show Lost aired from 2004 to 2010 and ran for six seasons. Its series finale is often considered one of the most divisive endings in TV history. However, the show is saved by one crucial aspect: its character-centric story. Throughout the six seasons, Lost's characters are engaging, sympathetic, and well-written. The focus on the characters allows the ending to work, as it rests on their shoulders and the story built around them.

One commonly misunderstood aspect of the finale is the flash-sideways universe introduced in season 6. Some viewers mistakenly believe that everyone was dead the entire time, but the finale explicitly states otherwise.

The flash-sideways universe serves as a plane between life and death, where the characters reunite before journeying into the afterlife together. The show's development of the characters in the final season helps make the ending make sense.

A reboot or remake of Lost would not work due to the strength of its characters. The divisive ending, which provides a heartwarming and emotional conclusion for the characters, should not be tarnished. Additionally, the characters' journey into the afterlife at the end of the series makes a reboot impossible.

Furthermore, the show has not aged enough to warrant a remake, and recreating the exceptional character work of the original would be a difficult task.

In conclusion, Lost's divisive ending is ultimately saved by its character-centric story. The well-developed and engaging characters make the ending work, and attempts at a reboot or remake would not be successful due to the strength of the original characters and the satisfying conclusion they receive.
