Lost and its similarity to Titanic

Even though Lost ended a week ago, I still find myself thinking about it and talking about it with Friends. Regardless of how you feel about the big reveal, that's the mark of a quality show - it gets people talking. Well, recently I was listening to the radio and the 1990s classic "My Heart Will Go On" from Titanic played and I realized just where else I had seen the idea of a shared afterlife.

As the biggest grossing moving of all time, besides that other James Cameron movie, most everyone is familar with the ending. Rose, after spending the last 3 hours reliving her time on the Titanic and with Jack, she passes away. In the afterlife, she's once again reunited with all those lost souls from the ship, even though she spent at least 50 years of her life married to another man and raising a family. Even though she spent decades with her family and husband, the most important time of her life were those days on the Titanic.

The most important time of the Lostie's lives were on that island. It's especially true for those who died there, but even those that got off that rock and led full lives after. For example, Claire got off the island and presumably was able to raise Aaron herself and become a fully integrated member of society again.

Do you agree? What are your thoughts on the shared afterlife that Lost put forward in its finale?
