Fortunately, I do not judge a film merely by its technical excellence. Other reviews seemed to overemphasize the limited script, miscasting, lack of focus, etc, that this movie supposedly represents. All of it may be true, and certainly if the movie did not reach me, I too, would come up with a barrelful of sophisticated reasons why it didn't work.
The problem is, it moved me. It touched my heart in just the right way, and left me once again, with a longing have known everyone who ever lived, suffered and died.
Ah, the human condition!
The first half of the film was slow, and seemed to be searching for itself. But from the time Robert entered into the home for the insane, it became engrossing. I thought the story of the "Lost Valley" was poignant and worth the whole movie. All that came before was necessary background for all that came after.
So...not extraordinary, not outstanding, but quietly satisfying and definitely memorable. A little gem -selected with care- to share with those you love.
