Like in a Kafka book, a character is cool and rational, but suddenly sees everything around falling down. He painfully sees that the mystery of evil can't be explained by the faith in God or by the bare cause-effect paradigm. Mourning is indeed more painful, if you can't explain why an accident happens, and the movie is about this (or, my interpretation). Despite something ingenuity about computers and despite the low budget, the movie is tremendous and wonderful.
