the article's author is basically playing at hapless fanboyism, of the show, not the books. i doubt the author of the article actually read the books because none of the justifications of the changes as deviations from the book, make sense. Example: about taking lolly out, and making a near rape of sansa during the riots "I felt that this helped bring home the horror of the riot by making it a character we care about. "
EVERYONE hated sansa at this point in the series.
the girl who actually gets raped during the riot, she later has a rape baby.
