It's a tricky film to review. You can look at it on two levels. On one level, the FFVII freaks who've played the game and are already intimate with the story. On that level, I loved the movie and got a kick out of seeing all the characters we love being brought to life.
But on a separate level, if you walk in with no prior knowledge you're going to absolutely hate it. This movie can't exist on its own with numerous inside references, no real story arc or plot. The only thing holding this together are the beautiful fight sequences.
