Celeste & Jesse Forever (2012) via IMDb.
Well written (by Rashida Jones) and acted. It explores some of the modern aspects of relationships: how to handle friendship, what to fight for, various new aspects of dealing with friends, exes, etc.
The important question and scenes to me were the ones that dealt with: is it a question of being right or being happy. They seem to present that they can’t coexist.
Also, that good things are worth the fight/work. Unfortunately, people these days have a hard time learning that most things worth fighting for, take a fight to get and maintain. Better, they learn it too late.
