Uchuu kuubo Blue Noah or Thundersub is one my fav anime when i, as young, the anime produced in1979 & it's dubbed to multiple languages including Arabic...
The show has come in the time when space operas are in their prime The time when star wars star treks was in their peak & anime like space battleship yamato, captain harlock & gundam ....etc go to make a bigger impact in the history of anime at whole...
But somehow, this show has felt down from mention when we mention the history of anime in that time, may be show similarity to Yamato or it being stuck with bigger show in that time or may be the show have ended after 24 episodes & never getting a sequel or remake until now....
Let's talk of the downsides, the story is similar to many space opera in that time although most of the events was in the seas instead of space the character are solid but not remember & the animation are outdated for a long time
in the other side ship design was amazing the music was great & many of the actions was cool...
For me I love the show & always a place in my heart I suggest to old anime enthuses who love show like these to get a try..... thumb ups!!!!
