The influence that the cinema exerts on the minds of those who visit it is at once beneficial and harmful. The films shown in the cinema are often very instructive and informative. Almost every film shows something about the activities and customs of the people in other lands. By seeing such films, one learns a lot about human activities. One also gains a better understanding of people of the world. Films which show the activities of criminals have encouraged many youths to commit acts or crime. Other films, too, such as those dealing with sex and other natural weaknesses of man, have corrupted the morals of many people. As a result, the governments of many countries have been compelled to interfere in the display and production of certain films. Yet, the cinema continues to retain its popularity.
