A movie never presents a story exactly as you envisioned it, but nevertheless, every movie version you see gives you new insights into the story.  This is a very Biblically accurate version of the Joseph story, not changing the Biblical story but rather developing it.  (For example, in this version, Potiphar believes Joseph is innocent of immorality with his wife, and Joseph tells him about his past as a flashback, not found in the Bible.)  The massacre at Shechem in Genesis 34 is included and shows what rotten people some of Joseph's brothers were.  The actors for the brothers do very well demonstrating individuality but also a group mentality, and they show powerful character change by the end.  It's interesting that the movie shows the brothers have really changed just by showing their eager attitude in blessing the name of God with their father Jacob ("Blessed be His name")!  The actor for Jacob does very well, too.  (The actor for Joseph is fine, too, but the character couldn't have too much personality, because every viewer has a preconceived expectation of what he should be like.)  The movie introduced me to an interesting idea, which is that Jacob may have been involved in preserving genealogies and stories from Abraham.  The Book of Genesis does have a much more continuous account of Jacob's life, whereas stories of Abraham's life are like disconnected snapshots.  So what I got most out of this movie was the interesting idea that the Book of Genesis was recorded before Moses' time.
