Unfortunately, I can't tell you if the rest was okay/correct. I generally assume the worst, but I'm mostly oblivious to historical accuracy (or lack thereof), unless history-savvy clear that up for me. ;)

I don't have any statistics, but I fear it didn't do that well - at least here in Germany. There was hardly any marketing and it got shitty screentimes even in the first week, so I doubt it was very successful. :/
