What was the point? (Spoilers)
Let me say up front that I'm a big fan of character-driven movies and TV shows, so it isn't as though I need an action-filled plot to make me feel that I've spent my time fruitfully. Nor do I need a happy ending, or even one that neatly wraps up all the loose threads. But I came away from this series wondering why I had bothered spending four hours watching it. Mei ends up back in London, still helping the activists in China, and sending items to her mother, but that's all. Those are both signs that she's caring more about other people's welfare, but overall, I didn't see any real growth or resolution or anything else. I even found her brother more interesting in his few scenes than Mei was in all of hers.
I'm curious to read other people's reactions now that you've seen the whole program.
