Im glad im not alone to realize how fashion-emo ff7 movies(and sequels) are, for me the most important difference was with zack death ( not the movie but similar ) his death was sad to watch, no music, just the sound of the bullets killing a dying zack, he looked pathetic at this moment and that made his death even more awful, two guys shooting a young man full of dreams and projects.
In crisis core, he is smiling vs 65456776555 soldiers shooting at him, where is the sadness in this trash scene? they totally ruined one of the most epic moment, it was like watching a japanese remake of 300.
I remember a pessismist story, musics and background for most of the game, if the movie was supposed to be fan service they failed
