Good story but too complicated for any non-ff7 player.
For a 3d rendered movie, this movie has proven that 3d could do so much more. The developers must have put alot of efforts making this movie. Not to worry, unlike the failure (spirits of the wind) movie, this movie will make a great addition to your other movie titles in your bookshelf.
The 2nd disc also features another part of the ff7 sequel which will explains most of the stuff before FF7. Everyone should get the show to experience the good graphics and movie effects.
