Food for thought

I actually enjoyed this story.
Not because of the mayhem and chaos, but because of the story telling and the message it was trying to impart.

For me, the least realistic aspect of the story (besides the genius mother-son sociopaths) was Nezu and Mirai.
But that's okay.
Maybe even necessary.
Without those two, representing idealistic characters (they could've been the mc and heroine in a shounen manga) , the story would not have gone so well
