"The Tree of Life" - Unusual Movie

"The Tree of Life" - Wow!  I am not sure what to think about this movie.  Visually, it is spectacular, sort of a kaleidascope of beautiful images.  The story is of a family with three sons growing up in Waco, Texas in the 1940's.  There are many scenes that struck me as perfect images of the time: the bright colored aluminum glasses the milkman delivered in the summertime, filled with cottage cheese; the boys haircuts; the clothesline filled with gently blowing clothes.  Brad Pitt is wonderful as a father of that time, part tough, part gentle.  The mother is idealized and fun.  The three boys ring true to the period also.  I am not sure of much else...what exactly was the point?  In some ways, watching this movie was like meditation, my mind kept flicking through the images, going off on thoughts of my own, refocusing.  I count any movie a success that causes me to think about it and wonder what it all means.  Sean Penn moved through the movie but I am not sure what he was projecting.  I may have to see it again.
