Why so many negative comments... Yes, the episodes aren't very dynamic, and this isn't something like Interstellar or other sci-fi movies. I also expected a more serious drama with more global goals, but despite my expectations, I can still praise this drama for its beautiful visuals, good plot, interesting characters, and funny moments. And what I absolutely love are the OSTs—LISTEN TO THEM (Honestly, I wouldn't be lying if I said I listen to them all day long)
