The film is passable, with a few interesting details sprinkled throughout. Apparently, Brad Pitt’s agreement stipulated that the ending couldn’t be altered when he first read the script, and he recalled a similar situation from an earlier project. Ultimately, the ending remained as written, despite some suggestions for modification—apparently, people felt it was excessively dark at that point. It's certainly sufficient entertainment to fill some time, and I likely won’t have any regrets about watching it. Maybe.
