Not historical
This movie was a disappointment on finding it was "based" on memoirs and was just too fantastic to begin with. Aside from the desire to kill the damn kid, or at least slap him silly, I found the movie too long; the ending was dragged out far too long. Great acting or overacting, as you will. John Malkovitch turned in another great performance, but no one else did. For a far more accurate movie about internment camps, watch "Three Came Home" starring Claudette Colbert.
