In fact, I have heard of this movie since I was in high school, but the name of this movie “Dead Poets Society”has made me deterred. Because at that time I thought this movie would make me feel depressed. Finally, because of the teacher's recommendation, I still watched this movie. After I watched this movie, although the movie still made me feel very depressed, but it actually gave me a lot of feelings. There is a character in this movie that makes me very profound, that is, Teacher Keating. He is a teacher with a unique insight into education. His class is different from other teachers. His class atmosphere is very lively and always full of laughter. He encourages students to look at the world from different perspectives and don't limit their points of view by the views of previous people. Indeed, in many cases we always feel that we are too limited to books or authority. We always deliberately deny ourselves. We also feel that we are "frogs at the bottom of the well". Therefore, we must know how to jump out of our own box and look at the different aspects of the world. Teacher Keating said:“But only in their dreams can men be truly free.” I really like this sentence. There are too many things we can't predict and can't change. Everyone wants freedom and doesn't like restraint. Perhaps only in the dream can there be a chance to be satisfied. And he also made me learned to be happy in time and cherish the happiness of the moment.
