When we watch a live stream, what are we watching?

I thought I was going to watch a simple youth film, but I was a little surprised.
The film is mainly about a popular live game in New York, "Nerve", which is played by choosing two identities after entering the game: player or audience.
Players accept the challenge from the audience and receive the corresponding prize money when they complete it, and the two players with the largest number of spectators in the end enter the final, and the winner receives the full prize money.
Of course, there are rules for the game, and the rule of "live broadcasting" is that the player must use the mobile phone to broadcast live the whole process, and the only way to eliminate is "elimination" or "exit" and not to inform anyone.
Vee, played by Emma Roberts, and Ian, played by Dave Franco, are the two most important players in the game.
Vee, a high school girl, is an ordinary and well-behaved girl, and her greatest pleasure on weekdays is to "spy" on the male god JP in the school.
Her friend Sydney is addicted to the live game, doing all sorts of daring things to attract viewers. Influenced by it, Vee, who is accustomed to being a bystander, also joined the live game and became a "player".
Her first adventure was to kiss a stranger. After the challenge was successful, she discovered that the stranger Ian was also one of the gamers. The live broadcast of the two of their adventures went from being fun and exciting at the beginning to gradually getting out of control.
They must work together to escape this desperate livestream.
Although it is a 16-year-old film, it has a sense of ironic familiarity when it is put to the present, why? Because what happens to the players and anonymous users inside is a microcosm of the current online world.
The drawbacks of the anonymity mentioned by the heroine, I believe many people have a deep understanding of it. Everyone wears a mask of positive energy in real life, and when they go online, they hide in the dark to vent the most extreme and negative emotions, and the most important thing is that they don't have to be responsible after venting, so they dare to be so unscrupulous.
