Calling this a "behind-the-scenes" or "making of" documentary is false advertising. There is nothing in this documentary that explains how anything in the show was made, filmed, composed, or any of those things that are staples for a good behind-the-scenes documentary. The only exception is a look at the puppet/mask designs for some of the aliens, but this is only a 2-minute scene.
Instead, the the show focuses almost exclusively on having each of the major actors talk about how they felt being in a Star Wars production. As a fan of the prequels, the first 5-10 minutes were interesting to hear about Ewan's original acceptance of the role, and it's nice to see Ewan and Hayden are such good friends, but there's no reason to drag out the feel good stuff and the "I love Star Wars" sentiment for a whole hour when they could be showing us some actual information about how the show was made.
