This is so powerful. I don't think I even drew breath while watching this! It's very impressive and inspiring. The acting is as striking as the dialogue. The unimposing music is a beautiful background. The church is a well-chosen and intriguingly controversial setting for it all too. However, it is that cut at the end (spoilers!) that seals the deal, finishing the film poignantly and gracefully with a lasting impression.
I've watched 'Think Different' and 'Still Life' too and they're just as experimental and interesting.
