What they share
Both films are directed by Tetsuya Nomura, and they both carry the neon soaked mood tag, and they sit in Action / Adventure / Animation / Fantasy / Science Fiction territory. If that's the register that drew you to Final Fantasy VII: Advent Children, the second film will land in a comparable space — through a different lens.
What Final Fantasy VII: Last Order is
You flee Nibelheim while Shinra burns it behind you then dodge their soldiers every step to Midgar. Shadows of flame and betrayal trail you the whole way. The film renders those smoke-black memories in stark manga lines that flash forward before settling back.
