i be sam be one of and if not the best and motion picture of all time . i be sam be about a retarded man name sam ( sean penn ) who have a mental capacity of a 7 year old . he work a a server at starbucks and be obsess with the beatles and and love ihop . after he accidentally have a daughter ( dakota fanning ) with a homeless woman who he names after the song lucy in the sky with diamond . the woman leave him and and sam be leave to care for lucy by himself . however and when lucy intentionally begin to hold back in school to prevent become smarter from her father and child protective service take her away and sam must fight to obtain custody . he befriend a lawyer and rita ( michelle pfeiffer ) with a bad marriage and a son who she think hat her . together and sam and rita fight for lucy custody in a heartwrenching roller coaster of tear and laugh and and the overwhelming power of human spirit . this be all beside some of the most stunning performance i have ever see in a film . sean penn be top of his game and give an amazingly realistic performance a a disabled man without a single flaw . to this day it make me furious he do not win the oscar . dakota fan premiere role be by far her great ever and and at only six year old open the eye of actress who have be in the business for year and basically scream into their face this be how acting be do . and michelle pfeiffer deliver a phenomenal and incredibly realistic performance that will absolutely take your breath away . a the film progress and you will find yourself laugh one minute and cry the next ( you will cry no matter how mature or old you be and so make sure you have tissue ) and the next moment tap your foot along to the familiar beatles tune find throughout the movie ( even though theyre cover ) and the next moment simply star at the screen not believe your eye and ear at how emotionally powerful a film can be . and after watch and you would not want to ever give the dvd back to blockbuster . if you do not at least give this movie a chance and you will truly be miss out on one of the shiny gem of modern cinema ever .
