I could really summarize this review into one line.
Reason to watch? Yuno.
Story: 7
I mean it's not great, but the concept of seeing the future isn't that new. While a future diary is different, there is some plot holes. And a lot of things that didn't make sense. But it was okay, because Yuno was there, so it was all good.
Art: 8
Yuno was drawn, so, pretty good art.
Sound: 8
Personally I liked the sound. And also Yuno was in the op. Both openings, actually.
Character: 10
Not characters, but character. The characters, emphasis on plural, were generic and shit. But Yuno, Yuno was the only reason I watched this show and the only reason you need to watch it as well.
Enjoyment: 9
Pretty fun to watch, although that 9 isn't including episodes 16-21, or something like that, where the story got really boring, and just stupid.
Overall: 8
There's not much to say. Just Yuno. Just watch because of Yuno. Yuno is love. Yuno is life. Yuno.
