The movie was painfully bad, and an insult to Heinlein in that they allowed someone with almost opposite sociopolitical views to take control of his IP (wrong, I believe, no matter where you're standing). The site doesn't work for me either.
I wish they'd make something decent off of the book, which was, instead of a cheap satire demonizing the military, a character/society study. It'd make a better movie than game, obviously, but they could make something fun off of the universe he described. Aged fifty years and the science fiction is still fascinating
