I think the goal of this filma was to show the strength of people who are fighting in the war and what some go through everyday. and really show that it isn't at all fun and games.
It isn't really much like slaughterhouse five but the main cahactter is quite disfunctional and hides from all the stress he is put through by drinking and acting super cocky, and in slaughterhouse five the main character is pritty disfunctional and escapes what is happening by traveling through time.
I don't think Mary would like this film mostly because of how grotesque it is but I think she whould be proud of the fact that it doesn't encourage war really it show how nasty things can get.
