I liked it until I watched the bonus features and commentary. That ruined it for me.
There were some historical looking documents and stuff that are just cobbled together in photoshop and shown for for effect.
(manuals and schematics that don't really exist and aren't based on the actual hardware, etc)
When they show pictures of conventions and meetings, often they are random pics of unknown conventions the filmmaker found on the web,
not pictures from the conventions he is talking about.
There was more along the same lines, but I no longer remember.
EDIT: it's on Hulu
