These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: Ennio Morricone at his usual finest throughout. It's worth noting the score has often received more recognition than the actual movie.
Complete Monster: Colonel GŁnther Reza, a near emotionless automaton who takes clear satisfaction in forcing Dr. Villiega to betray his friends, and then making him watch the executions. He's also the one who ordered the murder of Juan's children and kills Mallory at the end.
