Ocean of Adventure
15 November 2018 | by hellraiser7See all my reviews

I really love stories like that because they truly present of there really present how anything is possible and there really is a big world out there beyond the sight of our everyday existence.

This is one of my favorite anime of all time, it's also another under the radar gem. It was a hit for its time, but as time went on just like Atlantis it sunk down into the depths of obscurity. This show predates the show "Stargate Atlantis" and even the Disney movie "Atlantis: The Lost Empire" another under the radar gem.

I really love the storyline, it's was loosely inspired by Jules Verne's "2000 Leagues Under the Sea" as it takes bits here and there but really is its own story, as it really correlates to some of the pulp adventure stories of yesteryear, which I've always loved because they are very imaginative stories. Like with a lot of the pulp adventure stories they always play with the concept of what if, here it's the possibility of what if Atlantis truly existed and being able to go with some advanced sophisticated means you never would have thought possible in the present.

But what also stands out is its story format as it's the ongoing plotline format which wasn't common at the time but is now common place in shows like "Stranger Things", "Game of Thrones", "Battlestar Galactica" (revival version), which I thought was really cool seeing a show that had a continuously developing story but this format also stays true to the pulp adventure serials that always ended on a cliffhanger and never finished until the next film.

Music is great, I really love the theme song which is one of my favorite theme songs. I really love the animation which I think is very good, from the character animation but I really like the animation of the backgrounds bring out the pulp adventure quality from its locations, Atlantis itself and other things but also to help show a time when the world was still young. But also the vehicle and other scientific wonders we see from that tank Grandis and company ride which looks like a precursor version of the Tatchcoma's from "Ghost in the Shell" but the Natilis itself which is awesome looking and similar to the Yamato from "Space Battleship Yamato" but what I love about this ship is that it not just sails smoothly on the surface of the ocean but can go underwater and even up in the air which is cool because you can be mobile and have three kinds of warfare to utilize sub and ship warfare along with aerial assault.

The characters are all solid, each of them is three dimensional and there are some well rounded dynamics that you find yourself caring for them almost as you would a real person which is part of what constitutes good/great characters. And what I really like is how some of these characters show development making them feel a little more human.

Like supporting characters like Grandis, whom is a hot and sexy with that red uniform and hair. What I like about her is how she is just sassy (in a good way), she's fiery feisty. She's a person that seem like she's always looking for something but doesn't always know what it is, that I can emphasize with a little as I myself am a constant searcher. Though if there is a couple of things thing she's guilty of is being a little immature and having the mentality that she'll always get what she wants, but throughout the adventure she does exercise some maturity and that life don't go one way for no one.

Really like her subordinates Sanson and Hanson whom are sort of like a Bulk and Skull from "Power Rangers" only both are smart if slightly cumbersome and actually useful. Both really are a bronze and brains dynamic as Hanson he's the one that is inventive whom could literally put Ford to shame as he's invented a mobile tank before there even were any, while Sanson seems to have super strength. Really like the clashing back and forth between them but also like their interactions with other characters like Jean, let alone are actually useful which I feel fleshes both out showing their not just comic relief.

Electra whom is Nemo's number two I also really like, she a character also hot and sexy she's like the mysterious femine fatale in the noirs, she looks great in both uniforms though my fav is the white uniform which form fits her. Ahem anyway, I really like the she is serious as she seems duty bound but there is hidden depth to her and the feelings with it, which do play a crucial part in the storyline.

Jean is another of my favorite fictional protagonists he sort of could almost be a young version of Daniel Jackson from "Stargate SG1" or MacGyver. Just like those two he is highly knowledgeable in science, he's defiantly a person ahead of his time as he is always inventing and coming up with certain concepts that are what we have today. He's not a person of muscle, his best weapon is his intelligence which really is the best kind of weapon anyone can have as he is using his smarts and certain inventions to get out of some predicaments. But what I really love is he's has big dreams in having his inventions becoming reality but also a positive and ambitious outlook on both science and life. Nadia she's a solid character as she is feisty fiery, aggressive and has only her acrobatic skills and can-do aggressive attitude and strong feelings toward nature and humanity. Her only Achilles heal is she has a short temper and really jumps to conclusions about certain things too quickly. However, she is capable of being open minded and from everything going on around her she slowly but surely accepts the truth in the matter of things.

Jean and Nadia are one of my favorite fictional couples. I really love the chemistry between both Jean and Nadia, and it significantly develops. In a way it represents the relationship between both science and nature, the new ways and old values as both are in constant conflict but at the same time really do need each other. Both Jean and Nadia really are right for one another it sorts of reminds me of that in a Howard Hawks film as we see both really become more of a man and woman. Jean keeps her out of trouble or doing something stupid that could jeopardize both their lives, while Nadia she challenges him and really helps him be more assertive brings out an aggressive energy and strength inside him, he never knew he ever had.

I like how it's funny when both at times tend to misstep with one another mostly unintentional. We see Nadia's give Jean some grief intentional or unintentional because Jean sometimes steps in at the wrong place wrong time or says one wrong thing which leads to dire misunderstanding, this is funny because it's kind of true with some of us that don't really know how to interact properly or ask a girl out on a date right.

But what I like is how Jean despite the licks he takes he doesn't give up, he has deep feelings for Naida and he going to use everything in him to act and express them despite the result. Nadia also has deep feelings her problem is she hides them in a mask but also doesn't know the appropriate way to express them but is also impatient and acts and judges prematurely and foolishly. But throughout the adventure she learns to calm down and to be patient with Jean, and as both interact more she opens up more and lets Jean into her life which is something she hasn't done at all.

The show I wouldn't say is perfect there are a few slow spots in places, like for example that island arc was a bit long though making the show lose a little momentum as it was riddled a bit with filler. I don't think that was because of the story but because they had ordered a few too many episodes and had no choice but to use them. I don't know, most TV seasons and series have this fundamental problem. However, once they get back on the Nautilus things to start back up again.

I even like how the show meditates on certain issues like the slightly unsteady balance and relations between both science and nature, mankind and their place in both areas, the danger in progress and trespasses toward nature. But also, our constant need to evolve and explore beyond our boundaries and limitations, but at the same time keeping ourselves in check; as well as appreciating what you have while you still have it.

This hidden anime gem is a secret worth submerging.
