Answer
John Ruskin lambasted the art of John Martin. Martin was a painter of the Romantic era, and his work was often characterized by its depiction of dramatic and fantastical scenes. Ruskin, on the other hand, was a staunch proponent of realism in art, and he believed that Martin's work was overly sentimental and melodramatic. He also criticized Martin's use of color, which he felt was too garish and unrealistic.
