I think I saw a different movie than you guys. This thing was filled with terrible acting, bad FX, and a silly plot. Maybe it's because it's dated, I don't know. I re-read the book just before watching it, so maybe that taints my view, too. I mean, the HS stuff is in the book, but it's really brief, and nothing like the length it gets in the movie, and most of it focuses on the History and Moral Philosophy class. Carmen isn't even Rico's girlfriend. She's an interest he has occasionally dated (and so has Carl).
I'm having a hard time seeing the satire, to be honest. Robocop is clearly a satire. But if I wanted to satirize Heinlein, I would at least follow the basic structure of the book. I mean, the bugs aren't even sentient in the movie. They were hive-minded in the book, but they had starships, and the warrior caste fought with rifles, etc. Cutting that out cuts out Rico's self-examination, and his conclusion that the bugs actually have the same rights to these planets as they do. All of Rico's introspection is cut out. Satirize that if you want to call out Heinlein.
I don't know...I always read the book itself as a satire. The way it presents Rico as blindly playing a cog in a machine seems to call out the fascism, not support it. Rico accepts it in the end, but only after being hammered into it.
