Determine The Point Where You Should Stop

I think we should determine a point where the audience should stop watching, so they don't get disappointed in the end.

For me, it should be when Hui-Ju becomes the Spokesperson's interpreter live and side-to-side (I don't remember the event). Stop after the speech done.

(It is still watchable for like 1 episode after that event, but what for? The plot is pointless).
