To fully understand what i am talking about in here you should watch the "Tropes vs. Women: #1 The Manic Pixie Dream Girl" (http://www.feministfrequency.com/2011/03/tropes-vs-women-1-the-manic-pixie-dream-girl/) at The Feminist Frequency.
Tropes are the tool employed by some people in the creative arts which brings the person into the play that has an already complete set of well-known characteristics. "Manic Pixie Dream Girl" is one such trope.
P.S. Please note, that this episode is meant to be constructive rather than misogynistic criticism of the Feminist movement from an anarchist perspective.
