Nice documentary. The only thing that bugs me it, that the real "inventors" of this genere aren't mentiones with one single word.
"Diary of a Camper" by the Ranger clan started it all, even before Girlich released his Demo manipulation tools.
Also, not to step on anyones toes, but why the hell is the ILL-Clan mentioned in every friggin piece you read about machinima? Yes, hardly working was a nice flick, but it also was the only one by ILL afaik.
and, before i forget it, why didn't they mention the planned Animated series based on Masamune Shirows Appleseed, that will be produced using a modified game engine, or the incredible Anacronox?
