Not amazing, and that's me being generous. Supposedly set two years after the fight with Gargoyle, this is the story of a Neo-Atlantis remnant group trying to start a world war, with Nadia getting caught up in it by coincidence. The animation quality is worse than the main series, but better than the worst of the Island Arc. It comes off as a direct-to-video sequel to a highly polished animated feature film. Roughly 30 minutes at the beginning of this movie is filler/clips from the plot of the TV series. I guess budget constraints did not allow for them to actually animate 1.5 hours of new material...It would explain the animation quality too.

Many characters are missing without explanation. Of the main cast, King & Marie are never mentioned or referred to, nor any surviving members of the Nautilus (you'd think at least some of them might be interested in stopping Neo-Atlantis remnants). Of the returning characters, Jean and Nadia are more or less in-tact (though Nadia has decided to live apart from Jean until she can support herself - kind of weak motivation, but it's something). The real problem I had was with the Gratan gang who acted like it was episode 1-5 of the original show; completely out of character for what they evolved into over the course of the original show. It left a very bad taste in my mouth.

Actors do an okay job, but there isn't much to work with. The villain is trite and forgettable (yet has the gall to call Gargoyle the loser...). Shuichi Ikeda (best known as the voice of Char Aznable) shows up in a bit part. I'm not sure if it's because he's very expensive to hire, or what because he rarely seems to show up in anything for any large roles outside of Gundam... I'd say it's a shame, more of him might have improved the movie, but then again I don't think there was enough substance to do anything with.

Overall, this movie isn't worth the time it takes to sit through. The original show ending is a far superior conclusion and you shouldn't bother muddying the waters with this. I'll just pretend it does not exist...
