There are three different endings officially, one is when wolverine is in japan in a bar and the bartenders asks him if his drinking to forget where he answer I am drinking to remember, 2 is deadpool reaching from out the rubble to grab his head and the head comes back to life and whispers ssshhhh to the audience ( breaking the fourth wall which he does in comics, and the last one is similar to that one except a figure in black unseen because of the camera walks up to deadpools head and says " who the hell are you suppose to be" and the camera pans up to his face revealing him to be the real deadpool. More.
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.
