I really much enjoyed this, even there were some unconvincing parts (e.g. "why would we need iodine"). I even believed the main story, even it was much more scary than what we learned in school and what I have read.

There was a great article in a biggest Finnish newspaper Helsingin Sanomat that told how false the plot was. There were exaggeration and even rumors presented in small and big things.

You should enjoy this as entertainment, not as historical lesson.
