Well, I had it recorded, so I just watched it.
I thought of it as pretty off, but it's an interesting turn to take the show. The Temporal Cold War is a nice tie in. I'm also fairly handy with German, so it's a treat to be able to understand some of the lines.
The real question is this though: what did you think?
I thought it was a great episode. And I think this arc is going to be one of their best yet (even though I'm not a big fan of their medleling in the time line). Hopefully when they've fixed it most of their other transgressions will have subsided.
How was it "off"?
