39. Lost
The TV series Lost transported us all to a mysterious island with a band of castaways who survived an airplane crash. The cosmic show first premiered in 2004 and gripped audiences with plenty of mysterious storylines, awesome characters, and multiple plots until 2010.

Part of the appeal of the series was that the island was also inhabited by an enigmatic group called the “Others” and each episode was crammed with mysterious clues that left the audience hanging at the edge of their seats. People are still dazed and confused about what the show was really about, which is enough to make us want to watch it all over again.
