How to evaluate Shakespeare's artistic achievements?

Most of Shakespeare's plays are based on old scripts, novels, chronicles or folklore, but they have been rewritten with their own ideas, giving new, rich and profound contents to the old themes. In artistic expression, he inherited and developed the three traditions of ancient Greek and Roman drama, medieval England and Renaissance European drama, and made creative innovations in content and form. His plays are not bound by the three laws, break through the boundary between tragedy and comedy, strive to reflect the true nature of life, and dig deep into the inner mysteries of characters, thus shaping many typical characters with complex and diverse personalities and vivid images, and depicting a broad and colorful picture of social life, which is famous for its profoundness, poetry and philosophy.

Shakespeare's plays are popular plays written for the British stage and audience at that time. Therefore, in the18th century, it was criticized by the classicists represented by Voltaire, and was arbitrarily deleted during the performance, because it was a blend of sadness and joy, appealing to both refined and popular tastes, and free in time and space, trying to mobilize the imagination of the audience and make up for the simplicity of the stage. It was not until the beginning of19th century that the real value of Shakespeare's plays began to be known under the discussion of critics such as Coleridge and Khazri. However, Shakespeare's performances at that time were still often included in the model of five-act drama. At the end of 19, W. Bohr and H. glanville Barker strongly opposed the spectacular tradition of Shakespeare's performance at that time, and advocated that the Elizabethan theater should be performed without setting to restore its inherent characteristics.
