I did not expect the ending at all... I really liked the world building and art style, and the animation is amazing honestly. The plot development was so good too and I think that this is both a plot and character driven anime. The character development of the main character, David was good and I really liked the found family trope in this. He had always been an outcast and finally, for a while he belonged somewhere. So for him to basically lose everyone dear to him was very heartbreaking. About his romance with Lucy, I gotta be honest, I didn't really care about it and I much preferred watching the development of his relationship with his crew. His entire crew had died by the end of the 10 episodes and the final episode was seriously such a shock to me. Like David had always just given and given and given and he was gone too soon. So depressing.
