This review is SPOILER FREE.
Also, I wrote this when there were 6 episodes aired.
I don't usually watch ongoing anime (except for Fairy Tail, Naruto and Bleach) because I want to devour a series in one huge gulp.
But I think I made the correct choice when I began watching Mirai Nikki. This show gets better and better every single episode and the fact that I have to wait a whole week to see what the heck happens next, only serves to increase my enjoyment of the anime.
Right, back to the review.
The story is very clear but, at the same time, very thought inducing. The first episode already oozes with storyline potential.
The animation (especially in 10 bit form) is exquisite, with dual lighting, shadows and extremely well done Higurashi eyes. :).
The sound (the Opening in particular) is very adequate, the hard j-rock succeding in raising my adrenaline levels every single time :).
The characters...Yandere, why u so scary? :D Honestly, Yuno makes and brakes the whole show. Yukiteru isn't that bad, although in the first few episodes has Shinji-like moments, but, overall, he evolves pretty nicely.
The atmosphere is suffocating and you can actually feel the character's desperation.
In conclusion, if you want a mystery/thriller show with good storyline (the manga is over, so we'll actually have an end), awesome characters (did I mention the yandere? :D) and pretty colors (I mean: good animation :D), you should really watch Mirai Nikki.
