This movie made me feel like I had the flu at Red Lobster. This is an abomination, the animation is crude, the voice acting is terrible, the story line was illogical, and the talking spring fish with the Broad Way Techno Music was more than an abomination, I felt nauses at the sight of the musical number. The whole series was a failure, being a complete slap in the face to anyone who dies aboard The HMS Titanic. Somehow the director who I am assuming was either drunk or high came up with this crazy story that somehow everyone AND I MEAN Everyone survived the worst passenger ship disaster in history. The story begins with a research vessel lowering a byth-something into the water honestly I cant remember what the heck its called however I do know that this thing was invented in 1925 but this movie takes place in WWI which means this whole scenario is inaccurate. The point is, its a submarine of some sorts that is tethered to the surface via ropes and air tubes. It involves the characters from the last movie but all with different voice actors. For some reason a rapping shark hates the color yellow which is why he cuts the tethers to the sub thing, they all suffocate and pass out, which would have been the end of it, but some stupid massive dog octopus thing, the size of an oil platform cant get the sub from getting back to the surface because reasons, but it attracts the attention of some Atlatians who cant mind their own business, and unfortunately save the characters who aren't memorable enough to remember the names. They take them to Atlantis and give them elixirs so they can live forever, bla bla bla, whatever. And then the spring fish gives the a musical number in a ball room full of life size living toys with techno music and CLASSICAL MUSIC. It was so bad I think they just gave up. I also think this is what the Italians think we Americans are into, trashy techno. And for some reason there is a battle with the life sized living toys and some whaling dudes from the last movie or something. And then for some reason WHEN THEY ACTUALLY GET TO FINDING THE TITANIC it is not broken in half even though it did in the last movies. And another musical number, and the movie ends. There is probably some explanation for how bad this movie was, maybe it was a test for some subliminal torture being tested on us by a neo-fascist group trying to overthrow the government. OH YEAH the rapping shark scene.
