I wish I remember what critic said this, but the quote goes something like "The point of Starship Troopers is how you feel about seeing Doogie Howser in a Gestapo uniform."

Personally, I like the movie a lot. I never read the book (I like some of Heinlein, but not much,) so I had no emotional investment going in. Aside from having terrific SFX and some truly exciting battle scenes, the movie is hugely, and savagely, funny.

Good stuff:
-- All those great news bits scattered throughout the film, as if Fox News controlled the Internet. Razor-sharp satire.
-- The improbably beautiful-looking cast of main characters, providing the merest, gentlest, goofiest hint of some sort of "master race" theory at work. Combined with Michael Ironsides' character expounding on the cost of citizenship, the film upends the harshest of Heinlein's tendencies by mocking instead of preaching.
-- The way-cool homage to the climactic battle scene in Zulu.
-- Denise Richards. Yum yum.
-- The creepy S&M homoeroticism of the whipping scene; again, turning Heinlein's worldview of its ear.

That's all it comes to mind immediately, and I can't think of anything really bad. Obviously, it's a hard R-rated movie; it's intensely violent and definitely not for kids. Nor is it, I think, for the satirically tone-deaf. It works okay as a sci-fi action movie, but it works even better as a very black comedy with sci-fi trappings and great action scenes. Plus, it's got Denise Richards.

Just my two cents.
