I'm not going to pretend I understood the meaning the author wanted to convey with this show. Sonny Boy is the story of a group of students that get lost in an alternate universe, this world doesn't work like our own. The time is messy, the rules not always apply and cats are more like Jeff Bezos. Characters are a mixed bag; you get the interesting ones like Nozomi and you get the boring ones like Nagara. What bothered me the most is time in this world doesn't work like you would expect, in some cases thousands of years transpire and our character's behaviors stay the same, as if they didn't change from past experiences. The story is a mess, one episode they spend like 12 minutes talking about invisible monkeys that play baseball, after that episode the monkeys are never mentioned again. The fight between copies of the same person divided the people, they've been fighting for centuries. One copy kills the other and then it's never mentioned again and our characters are as if nothing ever happened. The animation sometimes is clean and other times it looks unreal, janky and cheap. The sound is good in most parts, there is no intro song and the ending song is likeable. Characters have powers but these powers are not the main focus of the show, it creates conflict between the characters, which its okay but when this conflict is not resolved and instead of finishing the idea it's throwed away 7 episodes in it becomes very jarring. I do not know how I feel about this show, for one side I’ve never seen anything quite like this, on the other hand I didn't understand anything, was falling asleep and became frustrated by the lack of direction and purpose. I would only recommend this if you're looking for something very unique.
