Giving this a second watch not all that long after the first, and yeah, not something you need to see a second time, but I couldn't help myself. And though I now know that a third viewing would probably taint my fairly good opinion of this documentary further, I cannot say that a third viewing won't happen.
I watched this mostly for the DVD extras, but they really weren't that interesting. The only cut scene that should've maybe stayed in was the one about Aron Eisenberg's interaction with Avery Brooks, but this opinion may have more to do with Eisenberg's recent death than of it's need to be included. Though I liked the character of Nog, it was this documentary that really made me like Eisenberg. He seemed like a very down-to-earth, passionate person.
