Early in the film you notice the male superiority and arrogance. They consider the main character Ripley crazy and hysterical when she argues back about how truly dangerous these alien creatures are. The male marines make numerous comments about Vasquez, a buff "badass" girl trying to prove that she can become one of the guys. The most arrogant of them all was Hudson, who is later the first one to fall to pieces due to the fear previously hidden by his egotism.
Each character in the movie clearly represents some of the boundaries we fight in our society daily. There is Hudson the jock, full of criticism and superiority. He quickly loses his haughtiness due to the underlining fear previously hidden by his egotism.
