Han is kind of like Obi-Wan. He’s there to usher our heroes into this new world and to give us some backstory. Obi-Wan told us about how Vader and the Empire destroyed the Jedi Knights and Han told us about how Luke’s Academy ended up going to shit.

But he’s not like Obi-Wan. Obi-Wan was a mentor to Luke, who was often out of his element. Rey, on the other hand, was superior to Han at everything. She could fly Han’s ship better than he could. She could repair it faster and better than he could. Han didn’t mentor her in anything. There was no chemistry, because Han didn’t have a role in the film. He showed up so you could go “oh there’s Han Solo, I love that guy!” Then he just kind of takes the characters to this place, and then he just kind of takes them to this other place, and then he just happens to get killed. The end.

There was a moment where Han asked Rey to join his crew, and I thought that was a good scene between them, but it got squashed by her refusal. It would have been so much more effective if her character had wanted to get off Jakku, and a backstory of her loneliness had been played up leading to that moment, and then she accepted Han’s offer. That would have created a far more significant bond between the two of them.
