My favourite of the 4 is Mad Max 2, alternate title The Road Warrior.
Until this year, I didn't think any Mad Max movie would ever dethrone Road Warrior. But holy crap, Fury Road did it! A simple story that is effectively stretched out to two hours by incorporating it into the action scenes, great characters and themes, breathtaking cinematography and music.
Everything was just wonderful. It's probably even in my Top 3 action movies of all time.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
