how would be the perfect ending for titanic,?

In the best of all possible worlds, the Titanic would never have sunk. So many people would not have been lost. As far as the movie goes, I would have loved it if both main characters had survived and been able to build a life together. That would have been a great sequel.

Don't know actually .. Maybe they both should survived and her fiance was not . maybe she should used that diamond and lived a happy life with whom she loves ! a lot of endings could fit here

I really enjoy this movie. My family and I (when I visit for the Summer) watch it as part of our movie entertainment. I think the perfect ending should have been that the ship never hit the iceberg, but since it happened I think that Jack and Rose should been able to live happily everafter with the diamond (The Heart of the Ocean).
