Notwithstanding that you've done a barrel of a job, mucker, I, personally, had a bit of a problem with it.
The thing is that I work with languages on an everyday basis. I speak fluent German and I also watched the original version of the filum in German. Considering Bruno Ganz is Swiss in origin, it's entirely up to his incredible skills to reproduce Hitler's Austrian/Hochdeutsch accent with such astonishing accuracy. As such, I found myself unable to appreciate your most admirable attempts to the fullest extent. However, full marks!
