The problem with the argument that the ST movie was a satire concerning the nature of war propaganda films is that the "satire" is so poorly done, because the military organization depicted is so ludicrously inept. It is tantamount to saying that the Keystone Cops are a satire of police work. They aren't, they are just slapstick. The ST movie wishes it could be as insightful as a slapstick routine.
To be a satire, there has to be believeability built into the basics of the story. Otherwise, there isn't satire, just stupidity. By making the mobile infantry incompetently stupid in training, organization, tactics, and leadership, the movie simply made itself stupid. Like I said, a group of retarded monkeys with lobotomies could have come up with a better movie - and they might have successfully made it a satire.
