I’m a cinema goer. And also I like watching films on TV or video. But I think, that watching a good film is the best relaxation. It is thought-provoking and entertaining. Now a growing number of people prefer watching films on TV to attending cinemas. There are wonderful comedies, love stories, science fiction, horror films, detective stories, and historical films on. There’s a variety of films available today. It is difficult to live without cinema. One fact is clear for everyone: cinema makes our life better. Cinema helps us to forget different problems. When people watch films, they have a rest. Some films take people into another world. I think it is a pure world, where usual problems do not even exist. Cinema is a great power, it helps us to understand our complex well. Cinema can leave nobody indifferent. It is so powerful that it provokes complex feelings. We meet a lot of people. Everyone has his own opinion about something and like most of us I have my own opinion too, for example, about cinema. Cinema is a necessary and important part of my life. It is my essence, my mode of life and my happiness. Cinema helps me to cope with difficulties and with incorrigible problems.
