The problem was, they used ANH Han for nostalgic purposes instead of ROTJ Han. ANH Han was selfish and didn't care much about others, which was perfect to set up Ben Solo turning to the dark side. ROTJ Han would give his life for his friends and even dedicate himself to the cause of the Rebellion. ROTJ Han would've done right by his son.
Except that he decided to keep Rey/Finn on his ship after they mentioned Luke was in danger. Before that moment, he was going to ditch them. This shows concern for others and is quite selfless in nature.
I'm referring to how Abrams rehashing ANH Han affected his backstory to TFA. He neglected his son. ROTJ Han would've made the effort to be there for Ben since the OT had already established him caring deeply for Luke and Leia.
Smuggling was also a sign of Han looking out for himself when he had no one else but Chewie. Post-ROTJ Han felt more like he would one day become an admiral under the New Republic. The conflict between him, Ben and Leia felt forced in order to wrap the new trilogy around a troubled Ben Solo and give us OT nostalgia.
I move for a vote of no confidence in Chancellor Kennedy's leadership.
