I am a little disappointed of this movie. Only a little.
It is part of a trilogy. I have already seen "Paradise Love" which was much more better. Ulrich Seidl (also) wants to shock with his movies, but nothing big happened there, but maybe just my expectations were to high.
When I compare it to Paradise Love, then I have to say that Ulrich Seidl is working with more pictures and less text. Usually its both shocking: the pictures and the text. But here I miss the text.
The movie was much more better in the beginning when she wants so missionize some random people in Vienna. After her husband got on the screen, I was annoyed of the plot that he is Muslim and her husband, and she his a hardcore catholic-person. I think it would be better if the plot would have gone into a different direction.
However I have to say that Maria Hofstätter is a great actress! I can recommend to watch this movie, but if you never have been in touch with Ulrich Seidl, you might consider to watch "Import / Export" first, then move on to "Paradise: Love" and then watch this movie.
I give that movie 7 out of 10 points.
