I saw this post a day after it was posted and checked out the documentary. I've been watching through it in chunks. It's been enjoyable. The practical effects are quite interesting to me. I remember having a realization that it was someone/team's job to do work like it for movies and TV shows when I was 9 or 10, after watching Jurassic Park for the first time. It's just amazing the kinds of techniques, materials used, and expertise that came about as more and more movies and TV shows.
I don't want to go into detail or ask questions until I've seen it all the way through. I will say though, that the editing style of the documentary has been enjoyable.
