Mungiu's excellent R.M.N. is a film that explores family relations and the topic of xenophobia.
In the final scene of the film, Csilla says "I'm sorry" to her friend. It's unclear what exactly she is apologizing for, and the film leaves it up to the viewer to interpret the meaning behind her words.
Was she sorry for leaving for Germany? Or, for (possibly) sleeping with the Frenchman? Or maybe, for not coming to dad's funeral?
