I agree. I think the Han Solo character, and the absence of Darth Vader are the two biggest things missing in the prequels. But, I think that is just the nature of the story that these two types of characters do not exist.
You didn’t mention Darth Vader, so, I won’t talk about why that sort of character has to be missing in the prequels. (Yes, Anakin is there. But, there isn’t a character who is very clearly drawn as the big bad guy who you should boo at everytime he appears. Sidious is there, but it’s not clear what is going on with him.)
Back to Han. The Han Solo character was the rugged individualist. The rebel against everything there was to rebel against. Even when he was about of the larger Rebel Alliance, the character was clearly rebelling against the constraints, and preferred to be on his own.
I think that is a character that fits in perfectly under the Empire. An oppresive regime that takes away people’s rights and freedoms. So, he rebels against that system, as everyone wants to, and he rebels against everything there is to rebel against. He is straight out of the Old West. With a vest and a pistol at his side.
But. In the prequels the republic and all of the planets are painted as being inhabited by much happier people. These people don’t seem to have a need to rebel. They are happy with their government and with the state of their lives.
So, I think it makes sense that a character like Han Solo doesn’t exist in the prequels. Furthermore, if Lucas had tried to create a Sololike character I don’t think it would have helped the film. First, I don’t think the character would have fit in with the way the galaxy is portrayed. Second, and more importantly, any actor playing this Han Solo type character would not have had a chance when being compared to Harrison Ford.
I agree that the Han Solo character made the original movies better and more special than the prequels.
But, I also think that adding a character of that type wouldn’t have helped the prequels. That being said, I have enjoyed both The Phantom Menace and Attack of the Clones immensly.
