What's Up With the Ending?
Well, the bad news is that the ending is super-sad.
We knew from the start that the ship was going to sink—that's just historical fact, folks—but then we lose Jack, too. We spend three hours watching Rose try to sabotage her own safety before she finally starts valuing life…only to lose her love.
Of course, the ultimate sign that Rose has grown is that she decides to keep going, even though her life coach/boyfriend is no longer around, and the good news is that she uses that experience to fuel big changes.
She abandons the whole life plan her mother had set out for her, as Cal Hockley's wife, and goes off to pursue all kinds of fun adventures. So, we get both happy and sad stuff in the film's final moments.
