Artists always seek for new ways of expression and graffiti is one of them. Some people are impressed with this form of art while others find it inappropriate and even criminal.
In my opinion, we can not help but mention that street art impacts the society greatly and becomes a real movement in modern art. Firstly, it is difficult to impress people today that is why artists use public places to draw attention. They try to make people think about urgent problems through their works. For example, Banksy is a famous street artist whose graffiti are known by millions of people all around the world for its truthfulness and unusual style. Once he even has his own exhibition in the museum. Secondly, every graffiti is unique that shows individual vision of the artists and their inner world.
People create incredible things as they are free from limits in drawing.
However some people disagree. They consider street art as vandalism because such artist break the law and spoil sights and private property bringing troubles to owners and the government. Besides, it causes rebellious moods among teenagers and affect their behavior badly.
I do not agree with this point of view because street artists are not hooligans. They could bright up the city if they had special places for it.
To sum up, graffiti is a form of art that is worth to be displayed in public places.
