I just finished reading Genesis. A few thoughts:
1) Joseph is the most pious character in Genesis, and therefore the least likable, when taking Genesis as a literary whole.
2) Much of Genesis concerns God favouring someone, and that someone screwing up, usually pretty badly, leaving God with egg on his his face, because, being God, he doesn't feel as though he can renege. But he always keeps trying, until he just kind of absents himself from the second half of the book, with lots of "God of your father" stuff, and not a lot of God actually being around. Compare and contrast this with Jesus' feelings about his apostles, which often borders on exasperation.
3) My favourite character in Genesis is Esau, in part because his name shows up in a disproportionate number of crossword puzzles.
4) If there is anything to be learned from Genesis, it's to never trust your siblings.
