Robert Pinsky, former US Poet Laureate, argues that it's a good thing that poetry is challenging :
Difficulty, after all, is one of life's essential pleasures: music, athletics, dance thrill us partly because they engage great difficulties. Epics and tragedies, no less than action movies and mysteries, portray an individual's struggle with some great difficulty. In his difficult and entertaining work Ulysses, James Joyce recounts the challenges engaged by the persistent, thwarted hero Leopold and the ambitious, narcissistic hero Stephen. Golf and video games, for certain demographic categories, provide inexhaustible, readily available sources of difficulty.
