I couldn't enjoy it as a satire nor a novel; it just wasn't exciting. It was simply a giant monologue by a depressed teenager spanning a couple days.
>>6 From wiki:
"The challenges generally begin with Holden's frequent use of vulgar language, with other reasons including sexual references, blasphemy, undermining of family values and moral codes, Holden's being a poor role model, encouragement of rebellion, and promotion of drinking, smoking, lying, and promiscuity."
Also, two major shootings were blamed on the book by the shooters claiming it inspired them to see the truth and do what they did. Multiple others were also related.
"Several shootings have been associated with the novel, including Robert John Bardo's shooting of Rebecca Schaeffer and John Hinckley, Jr.'s assassination attempt on Ronald Reagan. Following Mark David Chapman's shooting of John Lennon, Chapman was arrested with his worn personal copy of the book, inside which he had written, 'To Holden Caulfield, From Holden Caulfield, This is my statement'."
