I'll give this serie a 7/10, as future diary really had a strong storyline and character building, ... Music was average, btw the biggest reason i gave it above average ratings is because it's a very unpredictable and heart racing serie, which is the experience i always seek.
...but a big big bummber about this Anime is that it adds comical elements and light moments either right in between the serious/tense/thriller/suspence moments, often...breaking the consistent experience 😕, and also while the ending is happy, but it feels too alienated from the actual plot, and highly illogical (given how geniusly the future devices were written).
Overall, better for 1st watch,
but bad for a rewatch, cuz your intellect will start to breakdown the serie, and make you realise how a Well-put serie breaks it's own legs(plot) by the ending episodes.
Seriously by the time it was episode 27, serie had become a joke for me,
......infact i liked the side story of that eyepatch-terrorist lady(9th, was she?), ...she really had quite a ride till she became a Mom, i liked her character, atleast she had forged some principles through her life, unlike the Yukki guy. lol
