People are free to draw their own conclusions from the movie. The conclusions I drew are:
1. Blame game started right away ("Of course you are responsible. I was not even in the building" Bryukhanov to Dyatlov in the night of the explosion)
2. During the test some actions were taken with a complete disregard towards safety and consequences. Some people would call this reckless.
3. If this accident did not happen at Chernobyl it would have happened somewhere else.
