Okay look at this closely. Pay attention to 1:41, yeah it's "acting" but look at that the others in the room ( well the old cast) can tell she's breaking, and I can tell you truthfully she was not supposed to break down until the end of the song, but look at that. She broke down before the song ended, do you know why? Someone close to her died yet all of the cast is still there. They are still working even though one of their own died. The part where she starts crying is not scripted that was pure emotion of the lose she faced, so it's not "just acting" this was all the emotion she was feeling at that time. So it's not just acting its all the emotions that go into it. It's not easy. Don't judge people on how they act if you watch closely you can see what they are really feeling.
