Dry, that's probably the best explanation of what's wrong with this documentary.
While the stories are interesting and let you into another time of computers, when there was an almost hippy ethic to getting products to market, the interviews get a little boring after a while, major figures are introduced without fanfare so it's hard to keep a track on who was important and who's not. But the worst part is there is very little in the respect of showing off the hardware or the software, just a lot of talking heads.
example: "People are still programming games for the Commodore 64 and Amiga" - then show you no examples or even box art.
It suffers from the Star Trek Paradox. We must get to point A, the whole fleet is there ready to engae the big ship that's chasing us. Big ship disables the Enterprise and we never get the (hopefully) special effect laden space battle we were promised.
