While designs, clothing, monsters, characters and world building, locations, camera work and action show a lot of care and effort.. the script has bad pacing, boring developments, confusing plot-points and undercooked characters. It's almost NOT worth watching at all. It's just very dumb, with little to tie it in with it's great predecessor. Someone else here compared it to a Transformers movie.. I'd say it's even worse than that. Like a Mila's Resident Evil level of lack of self awareness. And reminded me of the worst parts of Advent Children (any FF7 fan should know).
Might as well watch it without subtitles.. enjoy the craft alone.
What a waste.
