Not sure which part is more depressing, nor am I sure which part has the funnier commentary.
I noticed a number of issues ( > 3 ) on original transmission but after the decades and reading making-of books, there were still things I hadn't noticed a few things SFDebris had.
Or hand't, such as how part one overlooks the identical giant holes in the ground from "The Neutral Zone" being the first time we technically know of Borg presence in the Federation (hinting at what is actually shown in "Q Who".)
