Only good things was seeing Cloud and Tifa and Sephiroth in HD CGi and the movie's fight scenes.
The Advent Children complete version has a longer, cooler and violent fight between cloud and sephiroth with blood unlike the normal version. The fight is cool.
The music in the movie is nice.
Thats it for the good stuff.
I love FF7 but I feel like all the spinoffs games and movies aren't canon. They retcon established FF7 scenes (Zack's death in Crisis Core and in Advent Children) and bring back characters that most assumed to be dead, Tseng and Scarlet are dead and it was assumed that Rufus of Shinra as well as Rude and the other Turks died in the tunnel in Midgar in FF7.
Also Spirits Within is older but actually looks better in terms of CGI compared to Advent Children.
Then you have dumb stuff like
Red XIII accent
cellphones galore
Mother this, mother that, I want mother! They know Jenova's name stop with mother all the time.
dilly dally shilly shally
They made Cloud emo. He was NOT emo in FF7 this is Advent Children making him this way.
Look up drinking games for the movie and take a shot every time Mother or Geostigma is said.
If you aren't Cloud, Tifa or Sephiroth enjoy your 10 seconds screen time because you barely see everyone more than that.
FF7 will always be better than its spinoff movies or games unless they make a direct FF7-2 with the same gameplay. Dunno how that would turn out.
Do I want more FF movies? Sure even though they might be bad I'm all for new FF stuff.
