Although almost everyone dies over the money, the characters of Hank and Jacob are the point of interest. Hank and Jacob form an alliance, without Lou. They work together instead of the "every man for himself" concept that is usually portrayed in these plots. Brotherly love is also a new addition to this. Hank never betrays Jacob either, Hank is forced to shoot him.
A femme fatal is also something I have not seen in a rags to riches plot. Sarah, a strange addition, wants Hank to just take all of the money and run. I wonder if she was put in to force Hank to stay(the baby), or if she was just there to make him more evil.
Also, every plot like this usually has the idiot that they pin the blame on. Lou takes that position. Usually it backfires with the idiot getting all the money, or something ridiculous. However, Sam Raimi decides to kill him off, along with his wife.
