Decent... but sadly....
Not good enough. It's been awhile since I actually reviewed a movie that was still under judgement, but this particular one, as I am a fan of FF7 and Kingdom Hearts, stood out to me. Unfortunately, you seemed to have wanted to make this movie Advent Children+Kingdom Hearts mixed in. Which, in theory might not be such a bad plan. However, the fight scenes themselves were rather stale... there were literally full 20 second intervals where all Cloud and Sephiroth's swords were doing was flipping up and down and there wasn't even sound effects of them hitting.... also the random FF7 characters and other characters joining in on rare occasion wound up becoming more of a distraction than anything else.... I mean the whole Cid and Barrett thing... wtf?
This movie DOES have potential, but too much time was spent making it synch with Advent Children music and the EXTREMELY long title sequence...
