Known for its action, violence, and exploring the dark side of veteran PTSD, Sylvester Stallone's Rambo franchise doesn't hold back. Beginning with Rambo: First Blood, in which John Rambo (Stallone) returns home from the Vietnam War to find his country openly hostile to his service overseas, it follows a veteran's struggle to reintegrate into civilian society while coming to terms with accepting that he can only thrive in conflict. Though the first film was a thought-provoking drama interspersed with Rambo showcasing his survival skills against local law enforcement, its sequels, beginning with Rambo II revealed his lethality against increasingly dangerous foes.
