My initial take away after watching it was pretty much the same. It's not a new story, it's an old one that is still going on.
But I think this documentary is a huge step in fighting for Palestine.
The documentary did a great job at repackaging that story in a format I think is more accessible to western audiences than just watching Al-Jazeera.
As for where I find hope, it's difficult, but in community engagement. Volunteering with existing groups or even just helping people on your own.
