It may well be that Netflix has a lot to answer for, so far as its impact on film-making is concerned, but short-term it delivers some wonderful stuff. There’s a moving documentary at the moment called Knock Down the House, about young Democratic candidates seeking to resist the Trump avalanche by standing as candidates for Congress. They’re not rich or respectable, and many of them don’t have a long political track record - but that’s the point. They’re at the sharp end, thinking “if I don’t do this, who will?” and watching them support and energise each other is really powerful. If you’ve ever been involved in a grass roots campaign of self-defence, you’ll recognise so much of this. The film moves between four candidates, all of them standing against the odds, but the triumph is the election of Alexandria Ocasia-Cortez, now famous as one of the squad. That she got to Congress is totally stunning. Now there’s the battle/tension/debate, between her and young, radical oppionenets of Trump, and the Nancy Pelosi generation, hardened veterans who see the dangers of going too far left, the way that feeds the Trump machine. There aren’t simple answers, but it’s still heartening to see that energy and passion actually record a win for once.
