Reno
The In Kraut
Saw this last night and absolutely adored it! Yes! This! Although... you make it sound as though our hero's human body was meant to be a metaphor for a crippled human society. Hadn't thought of it that way and I do hope it wasn't.
That would have been so clumsily symbolic, not even the occasionally ham-fisted Cameron would have stooped that low. The reasons why the hero is a paraplegic have purely to do with the character and plot. Films aren't necessarily puzzles of hidden symbolism that is supposed to be figured out by the audience. Using disability as a metaphor for a sick society would have been so crass and offensive it would have suited a Nazi propaganda film.
