Wikipedia goes further to say that the grandma group "celebrates [Mrs. Robinson's] character as a symbol of female independence and empowerment for a new generation of married women." Why,because it's fine to cheat on your husband if each and every single one of your needs aren't met? Empowering, indeed.
But looking over Anne Bancroft, we can see why someone would want to emulate her character in The Graduate. Not to fag out on you guys, but: wow. Gorgeous.
