I watched half of it, actually, last week. I'm from Belgium myself but only got like 1hour a week German for 1 year in school a long time ago.
I stopped in half because I felt we were going into detail so very fast (well, it's the setup of course, to start from specific words and dig into them), that I couldn't follow anymore.
But truth been told, I've never been the most linguistic guy anyway. So it's probably why I lost interest sooner than others.
