So would you say that the trilogy has three main plot threads. The Rebels against the Empire, Luke's reconciliation with his father and Han's redemption from Jabba the Hutt and general scoundrelness.

The thing I don't think works as well with the Han Solo sub plot is that the rescue from Jabba's palace is dis-proportionately large compared to the Bounty Hunter interaction in the first two movies. I understand that this also serves for Luke's progression to the title of Jedi Knight, but I think the cutting of the scene where Luke makes his saber lessens Luke's showing up at Jabba's palace to chew some bubblegum and to kick some butt.

Am I wrong about this?
