PTSD and Post-Modern Machismo
I couldn't help but feel bad for Todd and all the other soldiers. I think one of the major themes in this movie is the post-modern man and his clinging to the archetype of manhood born from the Iron Age; the Iron Man.
This movie is taking Post-Modern Industrial Machismo to its logical conclusion; a *beep* MACHINE. Funny how Machismo and Machine are similar linguistically (not to mention the overtly natural behaviors they associate).
Very interesting theme, even if poorly executed.
Almost a deconstruction of the Macho Action-Man flicks of yore (Arnold, Sly, Van Damme etc).
