The movie also focused on the action and put any message way in the back. And even then it was mostly segments paroding propaganda. Didn't say much on fascism, good or bad.
The movies are horrid, and are an example of "for sale to the highest bidder." The book was great. The first movie was actually not that bad. The second movie, "Hero of the Federation," tried and failed to be a messed up version of Apoc Now, whereby the Bugs secretly farmed humanity for food, and the wars were basically their dinner buffet.
The third movie.... [shivers]. The rights were purchased by nutjob christian fundies who made the whole thing into a Jesus allegory right down to Rico being executed between two theives and "coming back from the dead," via secretly being saved from execution. The bugs are wrong because they believe in the wrong religion and this is said in the movie itself. BELIEF IN GOD, in and of itself, saved the human race by uniting it. Literally crosses on space ships..... I mean that, google the ending of that movie.....
The novel, which is still on the USAF reading list, was actually about how democracy imploded when people wanted everything and voted for it, but with resource scarcity had no way to provide it. Everyone fought a massive war for "their rights." It nearly destroyed the human race. From the ashes came the Federation, whereby service meant citizenship and voting. The ideas was that the military knew what was really involved with running stuff.... The book is nothing like the movie and is told in field campaign style from the eyes of Rico a la more or less his journal.
