Caterpillar (2010) review

A lieutenant returns home from fighting in the second Sino-Japanese War not only without arms and legs, but without an ability to speak, while his dutiful wife tolerates his behavior, feeds him and has sex with him. I kept waiting for the wife to put him out of his misery, but she can't bring herself to do it, so most of this rather simple movie consists of him languishing in a state of misery and torment, haunted by his own behavior during the war (he's constantly flashing back to memories of raping Chinese women). I suppose Wakamatsu intends this as some kind of condemnation of war and the behavior of the soldiers, but that's more or less implicit from the very beginning of the movie - though the agony of the wounded soldier is apparent, it isn't enough to drive the rest of this to some revelatory statement about living with a disabled person, spousal abuse or even mercy killing.
