No masterpiece as it often happens. If I compare enjoyment level of those that I rated higher than others, I'd nominate Hyper Police as it's at least logical, easy-going and with memorable characters though episodic
Elf wo Karu Mono-tachi surprised me a lot with modern isekai concept and really good humor while having next to zero ecchi despite the plot - felt like a firm masterpiece during watching .
Koukaku Kidoutai is the second genius masterpiece I can proclaim , plus this season sees the start of Neon Genesis Evangelion even though its first half was not outstanding
Since Maruko-chan can't participate in the contest due to absence of subbed episodes, there are no other masterpieces, and among others I favor Armitage III
Again no masterpieces. As of decent ones, I'd say that Taiho Shichau zo is the one I enjoyed the most even though it's just franchise setup with 4 episode OVA .
