Everything in this movie. It's literally a fan-fiction with a tragic event slapped in. This movie could offend families of victims of the Titanic, and it's an insult to history.
even if this is an animated movie aimed at kids, the overall atmosphere is rather eerie, creepy and disturbing.
One of the most inappropriate animated movies ever.
Mild fighting scenes.
"Doggy Hell" is referenced in one scene of the movie. There is one character (The King Of Atlantis) who has no face, which might scare very young viewers.
