I strongly believe that movies and television have a great influence on people's behaviour. It is an undeniable fact that most people in the world have access to either a televison or a cinema theatre and do make use of them at a regular basis.Some of the ways in which such media can affect people are stated below. 
Firstly, The main group of people who are attracted to the television and movies are teenagers. This is the group that is most likely to change. They often try to emulate what they see on screen in order to be a hero themselves.It is common to see young people trying to be like their Idols.
Secondly, Each country or region has its own culture and it is necessary to preserve them in order to exhibit cultural diversity to future generations. There are a lot of programs and scenes that are being broadcaste on televisions and in movies that might not conform to the mindset of the local society. But sometimes young people get influenced by these scenes. They get a false impression that they should live their life the way people live in foreign movies. They tend to change themseves according to what they see. This might destroy the native traditions and customs, which is highly understandable
These are some of the ways in which people's behaviour can be afftected by mass media such as television and movies, but at the same time we can deny the fact that movies and television are very important in our lives.
In conclusion I would like to say that I'm a big movie fan and I personally don't see bed sides of movies and television. There are lots of movies out there which we have to watch in order to be interesting and intelligent.
