for those who were expecting a profound speech at the end of Nosedive
What you have to understand is that in order to give a profound speech on anything that was happening, the girl would have had to have a well-defined worldview that she could clearly articulate. Whereas we are just seeing a girl (well, woman) who is a bundle of insecurities, who hasn't really formed an opinion of her own on... well, a lot of things, who is just trying hard to fit in and get ahead. She doesn't have the inner strength or the personal philosophy to fight the gross social injustice (one could argue that in that reality no one did).
Her brother was the only person she could be honest with, and even with him she hasn't had any meaningful discussions on what was going on - so why would any well-formulated thoughts suddenly come to her, especially when she is so emotionally drained?
So what we see in the end is a jumbled mess of her feeling hurt, discarded, and knowing that there is no recovering from this, and yet being powerless to stop it because, self-destructive as it was, that was the only way she could deal with the crushing pain of what was going on in that moment. A stream of consciousness, so to speak.
I was surprised to find out, btw, that the episode was written by Rashida Jones.
