I gotta say that was absolutely fantastic. I have absolutely no significant complaints about this episode, and it actually managed to exceed my expectations quite splendidly.
The staff is doing a great job of transferring the source material to a visual medium, and let’s not forget the absolutely fantastic bgms that give the anime it’s own special flare whilst remaining very true to the source. The episode was gorgeous, and I felt they did a great job capturing what’s great about Planetarian.
