Just finished it, I have never looked into the science of how they were gassed and cremated but now that I have seen that, I don't know what to think.

That's exactly how I felt after watching it, it's a great video, but I wouldn't go as far as to say that it was a myth in all entirety.

The thing with the poor construction of the gas chamber and crematory itself was kind of a waste of time rambling on how it was poorly designed, because it was not designed to kill. These were bunkers and housing and all manner of storage buildings they clumsily tested and tried different ways of killing the prisoners.
