Gate: Jieitai Kanochi nite, Kaku Tatakaeri 2nd Season, much like its predecessor, makes me think about the advancement of technology. Last time, it was weapons. This time, it is transportation.
We started with running on the ground. Then we tamed horses. Then we drove cars. Then we took subways. And then we piloted helicopters. We, as a people, have made advancements in movement at a rate that we (figuratively and ironically) cannot keep up with.
The citizens of the Empire within Gate (reducing the title at this point) are still stuck with just horses. And, sadly, they are still stuck with a mediocre anime.
