If you arent the patient kind and like shounens and much pewpew and figths most sure you will not stand the ritm of this serie, but trusth me is rlly worth the watch.
what they wanted is situate us in a feeling of common life whit the monotone repetitive day and nothing unespected happening, once you are into it even thinking wtf whit this serie, whats the point? then the good start.
Imagine that for a casual in ur day at day you discover something that you never should find, then ppl start to die in ur sorroundings, there are alot of incognits and the only one that have a minimal idea of what is happening its you, but it also dont stop there, its geting worst, the humanity can get extint...
------
The char desing can seems common, but when you start to know them they have a very distinctive and great defined personality, everyone whit him own problems but whit a strong connection betwen them in the group.
Have to make a personal note about the blonde hikikamori (sorry im bad for remind names), i just love that girl x)
-----
The music isnt rlly great but it helps to manage the explained atmosfere and knows when get in a mysterious feeling when it have to do.
----
The art is good, in the two or three mini robot figths have nice efects also that mecha serie that they watch look very cool. For the rest the style is pretty much like steins;gate.
----
All in all, it is a GREAT serie that you shouldt miss, is not just at the category of it epic secuel but in some moments even better. Be patient just enjoy what ur watching, when you less spect will start to love and cannot stop watch.
Just the humble opinion of a fan that saw way to much anime x)
