I found the discussion on gathering the HD footage interesting, but it wasn't anything I didn't already know, given how closely I followed the TNG remastering process. I thought it was still worth sitting through though.
Quite a few people left the theater where I saw it during this part. It definitely felt like a bluray extra, and it was good that it came after because it was clearly for just the superfans. Personally, I was fascinated.
Well, I am extraordinarily mad at myself.
Ugh, I'm so sorry. We've all done this kind of thing, and worse. You can make it up when the doc is released to video/streaming and just throw a huge party instead.
