Why is Shakespeare called the greatest dramatist in the world?

His Universality:
Shakespeare is not of one age, but of all ages, not of one country but of all countries. His freshness is perennial, his appeal is universal. He is world’s immortal writer. He wrote in the Elizabethan stage and audience; but he is read and enjoyed even today not only by Englishmen, but by the English speaking people all over the world. His works have been translated into all the important languages of the world; and the films based upon his dramas continue to draw packed houses. His freshness and appeal seem to grow the more he is read.
