This film is excellent, surpassing my expectations in terms of the quality of the film-making and in terms of the depth of the story. Not to ruin the suspense, but the aviation difficulties of the film are more of a resolution than a starting point of the plot. The special effects could have been better, the women could have been less hysterically cruel, the ending could have had less Russian sentimental comic relief; but the movie is successful in telling a story about human beings. I would rate it even higher if the women weren't so shrewish, but that's because I like a bit of fantasy in the films I watch.
