Uh...What can i say....As much as I enjoyed 1st season, this is a total mess and I got no idea where all the praise for this disaster comes from.
Art and audio are ok and...thats about it. I wont even go into the story, cause no matter how interesting plot one may come with, with retarded characters that cant add 1+1 and seem mentally challanged. it will always be ruined. I've waited till ep 18 to be surprised about main villain and whatnot, but main characters are making huge mysteries about 2 things (Kagari and Professor), which are obvious from the 1st scene they appear. Its no fun when you already know of what will happen at the start of the series. And when i thought shounen protagonists are idiots, Rintaro beats em all. I never met anyone as dumb in my life, let alone engineers / scientists.
Story 1/10
Characters 1/10
