The Ending
This IS an interesting film, with some offbeat and good performances by a young Jon Voight, Robert Duvall, and Seymour Cassel.
I just re-watched it recently. I had seen it several years ago and have been searching for a copy of it and finally found one.
However, I did not remember the ending being so ambiguous.
So...now I ordered the book and I hope that it explains more about the end.
