Reading the synopsis, it looked like a heart-warming story of a broken family reunited via online game. However there is no such healing at all. It was good until Ep 5, especially due to the difference of art style between real life and game, but went somewhere else after the twist in Ep 6.
Good character design (not only their looks, but also their traumen and accompanied behaviors) and animation, but it seriously lacks coherence in the story. It shares many subjects with SAO, but failed to justify itself like SAO did. (For example, brain damage from headgear is accepted by everyone, and this show also borrows it. But there is not enough explanation here how AI can damage people in real world even though they are not playing that game.)
The worst is that it is full of violent and unpleasant killing with detailed portrait of dead body. Not recommended to those who are looking for happy story, or well developed storytelling. Only for gore fans. I can't rate this below average due to the quality of the animation, but to talk about the story only, it's 2/10.
