One could say this had a messy.... narrative.
To wit:
STORY/CHARACTER: The story is extremely messy and not well told. None of the characters are particularly interesting or fleshed out. Especially the ultimate villain. He's literally nothing and his mecha are just retreads of stuff from the Unicorn series.
There's interesting nuggets in the overall story but nothing to actually give this movie a reason to exist.
ART: Also messy. The designs are good, but the actual implementation and animation are not great all the time. Some returning characters look really derpy.
SOUND: Sawano score so if you've heard one of his OSTs you know what you're in for. Dub was fine. Not amazing just fine. Good overall sound design for the foley.
It's a fine ride (in theatre) but outside of the theatre its not worth it imo. It doubles down on the most controversial part of UC Gundam (newtypes) so if you're a 0083/08th MS/Thunderbolt kinda fan, don't bother. If you like the weird stuff in UC, you'll be more inclined to give it a shot.
Final rating: super OK/10
