"It's afraid...IT'S AFRAID!"
I've read this thread through at least twice and never went 'boi-ing' before when reading that--in fact I'm not sure I have a post here at all.
I have only the general memory of reading the book, thinking that Heinlein's weaknesses are harder to take in book length but still we love the guy.
Because the movie, with the exclusion of the action, is so flatly reactionary I got rather bored and aggravated with it and did not catch on in first viewing that it could be at all arch, outside of Michael Ironside showing up with fewer limbs on each appearance.
But now I remember that I felt a point was being made at the end when, although in the event the mother-bug had every reason to be afraid, it becomes known that the bugs can be afraid the on-screen consensus is 'good news--we can win' instead of what I felt inside me: If they can be afraid then they are like us.
In a conventional film there would have been a couple of wandering smart guys or wandering normally-curious guys who would have planted that thought earlier, I guess. Packing that thought into the last few seconds of a two-hour movie caught me off-guard. So off-guard I disliked the film generally until a year or so ago.
