It loses a lot from not being able to show footage. Some clips would have been great when they describe how improvised certain scenes feel, or to illustrate the way people were filmed from behind to allow for different/funnier lines to be edited in at the last minute.

Found out it was crowdfunded, so they likely didn't have the money, but it was still a bit disappointing. Walter and Cera are slightly missed too, as far as the interviews are concerned.

BUT: it's still a decent watch, and not a bad way to spend 75 minutes if you're a fan of the show. It's not technically great and it's lacking in the aforementioned areas, but it's a good celebration of the show, and the interviews with Hurwitz and the Russo brothers are particularly insightful.
