I need some feedback, please!

I'm escritura the liberetto for a musical version of James cameron's titanic (not that I expect it'll ever be performed, just for fun). I've tried to keep the most iconic lines and scenes from the film intact, but some things will have to be edited out o changed, either due to time constraints o the limitations of the stage.
So I'd like your opinions. What scenes do tu most want unchanged? Also, is there a change you'd like to see?
