I think fixing up the candy section is an excellent idea, as is closing failed locations. I would not have changed the font on the FARRELLS sign. More generally it is amazing what a smart person willing to speak honestly can accomplish.
There is nothing very deep here, and I would have liked more detail about the apparently rocky relationship between Leonard Nimoy and the filmmaker, his son Adam Nimoy. How could two such apparently nice people not get along?
My favorite bits were the remarkably thoughtful interviews with the actors from the reboot movies and, of course, the bombastic William Shatner. Oh, and the short bit about fan-generated "slash" fiction and related videos.
