It's a kind of special anime, because almost everyone must hate the main char, for his cowardness, crying for anything and defeatist style of solving problems.
But it has it's own style of storytelling and after few episodes, you should used to it and find it really interesting.
Story: Many good ideas and twists.
Art: The art is very nice, nothing against it.
Sound: Soundtrack is really awesome and many songs belongs to my "working playlist" right now.
Character: Yuno is the best one - no debate. The main problem is, that chars are still running around and watching to phones - sometimes i think, they even don't know anything, without phone's help.
Overall: First parts were kind of hard to watch for me(because the main still-crying char) but after that, it develops into very interesting (sometimes even intelligent) and good anime.
