For an ESL reader who'd gone through hundreds of 'best-seller modern English-speaking' novels and a high technical English fluency, fresh out of To Kill a Mockingbird (which was a shock, I had such a hard time at first) then Salinger and Hemingway, Gatsby was such a wonderful experience - I really didn't care for any character, plot, content... but the way FSF wrote was so compact and different. I can still remember the joy I felt, surprised that 'you can do that in English?'.
