Kershner directed the best of all the Star Wars movies. He butted heads with his former USC film student George Lucas on many aspects of production, including the increase in focus on the characters, and the movie, Star Wars as a franchise, and movie audiences are better for it. He also directed Never Say Never Again and Robocop 2.
I don't think adding Robocop 2 and Never Say Never again is good for his obit. Pretty much helped make Star Wars when a sequel could have been terrible. He was very engaging in his commentary for Empire as well as his interviews. His forte was more drama then action adventure anyway. He turned Empire down til he talked to his agent who told him, the pay day would set him for life. RIP.
His inclusion suggests we'll see more of Spider-Man than I was lead to believe. I had heard this was gonna be 90% Peter Parker. But there's no reason for Stacy to be there without interacting with Spidey.
