The over-arching plot isn’t much to speak of.
The beauty of this movie is in the cute and funny details. Vincent D’Onofrio plays the cockroach guy, with tons of hilariously gross makeup. D’Onofrio does a great homage to the titular character of Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb. Watch his arm movements as he drives the truck.
