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.
The NYT review does
not have much to say.
If this seems like the sort of movie that you would like, then you will like it.
