The story was good, the animation was absolutely superb. Some of the fight scenes could've been trimmed down in length, however it was superbly executed.
I can see why anime is so popular, although I only watch some now and then.
As someone who played the original FF7 and loved it, I disliked this. The villain for most of the movie was just a placeholder until they could shoehorn in Sephiroth (literally: they had to delay his appearance until near the end because his animation was expensive to do, what with all that hair). I didn't care about the placeholder villain and I didn't care about rehashing another battle between Cloud and Sephy. Since you didn't play the original you're coming from a different place. For me, it was a bunch of been there, done that.
At least they waited to have seph show up, unlike the remake lol ami right ? Im fall into the category of old aged fans that completely hate the the "remake" trilogy. But i understand i may be in a niche category
