(Lived the HACF era/story personally, so it was a poignant watch.)
What HACF got right, imho, was the collection of the various personalities that were attracted to the rising computer technology, of the era.
I've known plenty of Joe's and Camerons and Donna's, but the ones I chose to remember were the Gordons .. alas, there are the odd Gilfoyle and Josh stains among the sheets of memory too, though ..
