Arata naru Sekai: Mirai-hen (OVA)

Today I was randomly looking through my “Plan to watch” list of animes, and accidentally stumbled upon an OVA that I was really looking forward to. Since it came out only recently (October 2012) and I learned of it a bit earlier, I managed to completely forget to watch it. Now, though, I did, and my thoughts on it are mixed.
