The guy who performed it was also the guy who wrote it. Being a one-man show, he did multiple roles, and for some reason the actual story was punctuated by these weird, scenery-chewing soliliquies by Satan, which were not only unnecessary but also unintentionally hilarious, which is not something you want to say about a Holocaust drama. I'm sure his intentions were duly reverent, but as far as I'm concerned, it did the subject matter a grave disservice by distracting from the actual story and upstaging the character of Maximilian Kolbe. It's a common pitfall by unskilled writers to make the villian more interesting than the hero, but given the subject matter, it was just really unfortunate.
Moreover, you already had Nazis; how many villians do you need? Were the Nazis not evil enough for you? Did you feel that you needed to convince the audience that the Nazis were evil?
I don't know; maybe it was just me, although I did hear some other people near me chuckling, so that makes me feel a little better.
