As much as I enjoy indie, quirky, romantic-comedies (ie. Garden State), I really resent the female stock character which the industry refer to as the "manic pixie dream girl".
Drawing from the definition, the MPDG is often used in movies as the human catalyst for the growth and the development of the male protagonist's sense of identity. She helps the main character (often a tortured, anxiety-ridden male) overcome his immaturity and eventually inspires him to fully embrace all experiences and relish in all aspects of life.
Yes, MPDG are the proverbial "the one who changed my life" girls. I believe, they are also products of androcentrism. This means the portrayal of these type of characters indirectly undermines the complexity and the individuality of every woman. Fuck man! Not every quirky, bubbly and eccentric girl is just waiting to instil epiphanies and new found experiences in self-deprecating boys. I promise you LSD can achieve that same effect. Much less emotional entanglement as well which is probably useful, considering it can help prevent a full depression relapse when you finally do reach self-actualization and realize that you are a nothing without your MPDG. Oh yeah, and that you're also kind of a chauvinist.
I'm wearing eyeliner!!! WHOAZ!
