The ending sucked, and the justifications are wrong (SPOILERS)
Okay, so in the other treads people are saying that Justine lied to use the media attention to help the cause of saving the rainforest. Sounds plausible, until you remember something.
THIS WAS NOT HER CAUSE to begin with. It was FGM, which horrifed her at the beginning, and what she was talking about for a long while. Hell, the mutilation almost happened to her, you'd think there is SOME consequence, but no.
If she really wants to use the media to help, the obvious, logical and in-character response is to tel the truth and help further the campaign against FGM. This is what would have made sense in every way. She still uses the tactics of Alejandro of media manipulation, but also completed her story arc. That kind of ending would have been so much better in every way.
Not to mention, a way more satisfying ending too. Disappointed. Massively disappointed.
