What is the main message of The Truman Show?

Keith Du wants to calm Truman's recent mood by looking at photos of his mother and wife in the past, and reassure Truman that his life and environment are normal. However, Truman not only found that the Presidential Mountain was particularly small, but more importantly, he found that his wife Lu Mei folded her fingers in the wedding photos (Christians folded their forefinger on their middle finger to symbolize the cross, indicating that what they said or did was against their wishes and repented of their mistakes). He began to doubt his wife and decided. Sure enough, Lu Mei's hospital is even stranger. Doctors in the operating room can't operate, and lying patients are pretending to be sick. Truman saw all this. He knew that there must be something wrong with his wife and his family could not be trusted, so he couldn't wait to leave Taoyuan Island and go elsewhere.

Truman was going to Fiji by plane, but the conductor told him that there were no seats for a month. Truman wanted to go to Chicago by bus, but the bus broke down, as if everyone wanted to stop Truman. More and more suspicious that Truman around him also found the actor who beat around the bush in front of his house every day, he began to drive away from here. In the face of sudden traffic jams on the road, Truman was not surprised, and the car was gone after a lap; Seeing the volcanic warning on the roadside, Truman didn't believe it for a long time and drove directly through until the factory leaked nuclear. But what surprised Truman even more happened here: an unknown policeman actually told him his name when explaining the situation. Truman jumped out of the car and was forcibly stopped by several people. In the face of Truman's coercion at home, Lu Mei was even more panicked. Malone's permission saved Lu Mei. Truman made sure everyone was plotting. He had his own plan. ...

Truman seemed to be calm again, but one day he carried out his plan: he fled Taoyuan Island alone. For freedom and love, Truman embarked on a road of no return. When looking for Truman, Taoyuan Island revealed its horror. Everyone "caught" Truman, his parents, his neighbors and his brothers in the dark and instantly became murderers. The true face of Truman Show is so terrible and dangerous.
