Both movies include elements of space, and both movies shows the sacrifice and courage it takes to overcome adversity.

The main character is misunderstood, similar to the one in New Smiling Proud Wanderer. Similarly, both main characters question whether good people are as good as they seem and are bad people really bad. They come to the concept of a grey area where there isn't inherently absolute good or bad. They both try to follow unconventional ways of fighting. They both go through betrayal and trauma and eventually get stronger and try to fight their way through.
