So, first of all, "NTR-esque" warning for those thinking of watching this, before anything else. The show is also full of tasteless writing in many other places, many instances of which are never properly explained.

It is difficult to accurately rate Fantastic Children. Closure is partial, as it ends with many loose ends still unresolved. In the epilogue, many characters are simply completely forgotten to be addressed at all, as well as other open issues, as previously mentioned.

It has many side-stories going on in parallel, but in the end, half of it all turned out to be simply filler so that an already-slow-paced anime is even further dragged out, so that a story that is easily told in 13 episodes is stretched into 26 episodes.

It works great as a drinking game, however: take a shot each time they show a character's face trembling. Watch your liver. (show less)
