The real beauty of Bill the Galactic Hero was the scathing social commentary
. Despite the very non-serious nature of this series, it ranks right up there with Starship Troopers
and The Stainless Steel Rat Gets Drafted
as one of the best sci-fi
books of all time.
Central to this scathing commentary was the never-ending war with the Chingers, a lizardlike race portrayed as being enormous, endowed with venom-dripping fangs and motivated only by the desire to do bad things to humans. In actuality, the Chingers were tiny lizards, perhaps the size of a small domestic cat, and they were in fact rather intelligent and peaceful.
