This movie was made during the U.S. entry in WWII. Maybe that is why it leaves out the deaths that occur in the actual story of Steinbeck. The people in charge perhaps had the directive to make a light inspiring movie ("no heavy stuff, y'hear?"). I don't think it was in the spirit of the novel AT ALL. My low rating is based on the movie's lack of faithfulness to the novel AND the casting of Spencer Tracy in the role of Pilon. It was just not a good fit. Even if I could ignore the messing with Steinbeck's story, I could not watch Tracy's performance with any ease. It pretty much ruined the movie for me despite what I thought were pretty good performances by everyone else.
