Into the Wild (2007) is one of those movies that get under your skin and change your perception of life. Although the (real) story is quite simple, Sean Penn's criticism of society is a life lesson. Christopher McCandless is a graduate, young and idealistic american who decides to quit everything to walk into the wild. Along the way, he encounters a series of characters that shape his life. The poignant story of Christopher and his different experiences will totally change your perception of reality and life. If you haven't watched this movie, I highly recommend it.
