Why did the grin occur?
I am watching the movie, but am not clear as to why the grin developed, first in the father and then the son. Why would the father have such a horrible grin in his grave? Then, did the son develop it because of the emotional reaction of robbing the grave? Or are we to assume that there was a supernatural element, a curse of sort? Then, why did he, a seemingly kind farmer and good husband, become such a horrible person after winning the lottery with his father's ticket? Does anyone have any ideas?
