If you have watched titles such as Queen emeraldas, Captain Herlock, Galaxy express 999 then you are going to love Space symphony Maetel. It has 13 episodes which explains more about maetel and the queen of La metal.
I watched it and thought it was equally good to the other masterpieces made by Leiji Matsumoto.
The animation is well-done there are not many animés out there where they actually spend time on the animation, and who can't forget the graceful Galaxy express we see in the intro? I suggest you to buy it, cause it's one animé you don't want to miss.
