What does "revolutionary road" mean?

If you think that sam mendes only used this story to illustrate people's selfishness in marriage, then you missed the best part of this movie. After he died of miscarriage in April, Frank left Revolutionary Road and described how two neighbors treated the Weels family. When the old man who needed hearing AIDS to hear his wife's speech gradually turned off his hearing AIDS and stayed away from his wife's boasting, I finally understood the message that the director tried to convey in the film: that is, the unreliability of communication or language. Recalling that at the beginning of the movie, Frank drove April home, and stopped halfway to have an argument; There is also the climax of the film. Frank always tries to solve problems through conversation, and April always wants him to leave her. When people expect to save their marriage, they always try to find out the problem through communication. However, The Road to Revolution denies the significance of communication. When two people can't make sacrifices and reach a certain balance in marriage, when everyone is selfish and wants their life to develop according to their own wishes, communication can only be an excuse and dispute, and language can only be an excuse and accusation of selfishness. Therefore, instead of endless quarrels, it is better to calm down and choose the life that each other wants. So, after April's calm thinking, she can calmly face her husband the next morning and make her own decision, even though this decision ended in death.
