Why is "Critical reputation of Arthur Sullivan" trending?

Wikipedia Overview

The critical reputation of the British composer Arthur Sullivan has fluctuated markedly in the 150 years since he came to prominence. At first, critics regarded him as a potentially great composer of serious masterpieces, the long-awaited great English composer. When Sullivan made a series of popular successes in comic operas with the librettist W.S. Gilbert, Victorian critics generally praised the operettas but reproached Sullivan for not concentrating on composing solemn choral works and grand opera instead. Immediately after Sullivan's death, his reputation was attacked by critics who condemned him for not taking part in what they conceived of as an "English musical renaissance". By the latter part of the 20th century, Sullivan's music was being critically reassessed, beginning with the first book devoted to a study of his music, The Music of Arthur Sullivan by Gervase Hughes (1960).
