Sean Penn has been overlooked as a real actor - maybe because of his failed marriage to Madonna, or ... because of his political views? Who knows? At any rate, his performance as Sam has been much-maligned (especially in the U.S.) by so-called professional movie reviewers who compare his character Sam to Dustin Hoffmans Raymond in Rain Man. Well, PHOOEY on all that!
Penn portrays an intellectually challenged/mentally retarded dad (Sam), who loses custody of his 7-year old daughter Lucy (Dakota Fanning). Michelle Pfeiffer portrays a neurotic lawyer (with her own marital/child-rearing problems), who agrees to represent Penn in his quest to regain custody of his daughter. Laura Dern is Lucys court-appointed foster mother.
This movie not only does a GREAT job of attacking the U.S. judicial systems belief that a parent is not qualified to BE a parent unless he/she is educated, employed, & has normal friends - this movie accurately and unabashedly informs the audience that even though a parent IS educated, employed, etc., he/she has faults and challenges as well.
Despite some over-acting by Penn and Pfeiffer, this movie addresses real-life issues in the U.S. For example: Does mental retardation mean that a person cannot feel love, assume responsibility for oneself and another, be employed, and find happiness and joy in life?
The audience may - or may not - understand the significance of family in this movie. Ultimately, the viewer might find him/herself re-considering the concept of family during this movie.
Laugh! Cry! Better yet - understand!!
