It was a bit, but I thought it was the idea of the episode that was superb, not the execution, unfortunately.
As always I thought that there were things that could have been explained a little better of built up more.
It was not only that Bill's thing did not seem to work, but when Nina tried to use hers on Jonas it didn't work either. It was the aspect of religion being used, and twisted, that I liked, and the feeling that Jonas was not evil, probably believing he was doing the right thing.
When Rosen shot him I felt the impact was lessened by the fact that there has not been to much emphasis on Rosen being a man to whom guns are anathema. If we'd had that built up a bit the end would have had so much more impact (excuse the pun) that a man of peace was forced to use a gun to stop another man, who believed what he was doing was a peaceful improvement. (Well until he started setting the fire, but even then he thought it was a good thing.)
