Yes, the theory that suggests artwork is successful if it realistically imitates life is known as realism. This artistic movement emphasizes the accurate depiction of everyday subjects and situations, striving to portray life as it is without idealization or exaggeration.

Artists such as Gustave Courbet and Jean-François Millet are notable figures in this movement.
