How do movies or TV affect people?
For decades, television had played a very important role in our life.
It had changed our living and entertaining way in a great way, and I
believe that it had also influenced our behavior, both for the better
and for the worse. Firstly, movies and television make us more
violent. We are being accustomed the violent scenes on the movies
where there are brutal and icy faces with killing machines in their
hands. We are also forgetting that killing someone is permanent,
because the actors that were killed in a film can come back for
another movie. And finally, have you ever imagined that you were
Arnold Schwarzenegger in the “Terminator” when you watch that
film? Secondly, movies and television are making us less active. We
think that movies and television contain everything so we do not
have to go out to chat or play games with our friends. Staying in and
watching television for a long time can seriously damage us, both
mentally and physically. Watching movies is passive. We receive
everything that the director gives to us. Some of them may be good,
some may be bad but the most important thing is we will lose our
imaginary ability. And we may act like the actors on the movie. On
the contrary, we cannot oppose that television has good influence to
us. There are good movies that can make us change our prejudices
of something like “racial dividing”. Even education programs can
help us behave more graciously and wisely. Moreover, by watching
movies, we can temporarily escape from our problems and that will
help you reduce your stress. Anyway, television and movies have
their strong influence to our behavior.
Whether the influence is good or bad depends on how long we watch
them, what we watch and how we respond to them because everything
is advantageous in a way and disadvantageous in another.
