The movie was CRAP
Yes he tried and failed to satirize the book.
A good satirization would have been funny.
His movie was sad and incoherent.
It was a good sci-fi "B" movie, with a thin patina of Starship Troopers.
I have read that the it was pretty far along in development as just that, when the producers got the movie rights to Starship Troopers, and decided to just dress up their bug killing movie with themes from Heinlein, without spending the money to do the power suits.
Which is why you get a not terrible presentation of the franchise, and personal responsibility, combined with "action" scenes straight out the Jar-Jar Binks school of infantry tactics.
