This show is shit.
1. For show which is suppose to be grounded and mature it has no subtlety at all, all the bad guys are cartoonishly evil and look alike too, its slightly short of having huge arrow signs saying "I am the bad guy you need to hate" like they are doing shitty Tucker cosplay from Danny Phantom. A director at school what is he? a pedophile, A guy who adopted a child from a shelter? A Pedophile! A lady do runs the shelter? well she actually is a illegal weapon smuggler ha who are we kidding she is an obviously pedophile!! Their only reason of existence is to crowbar in the drama, they are shallow and boring.
2. Idea of criminals going through a rebirth and finishing their sentence as new men is a good premise but you need your characters to actually be fucking criminals. You can't have a redemption arc if guy is jailed for beating up teacher who raped his classmate, or Parent who tried to rape them or if guy survives of stealing food because his house and rest of his family got nuked or and stay with me here, Our guy getting jailed because he said something mean to his alcoholic father, who ended up killing themselves, so he feels guilty for father's death.
3.Solider who is most tolerable character doesn't get an arc. But gotta give a blondie his Justin Bieber arc.
4. This goes back to 1st point about crowbaring drama in. Show isn't smart enough do to in a way that is natural, so instead it has some absurdly illogical sequences and makes characters do some truly mind numbing actions.
A drunk guy assaults a bar owner, breaks property, assaults one of workers and gets beaten up and thrown out. Only for him to return next day with police who are arresting guy who kicked drunken because of "serious injuries he inflected" . Idea of serious injuries is dubious as we see him walking around with no scuff marks 3 days after the incident so whoever examined him needs to have their medical license stripped not to mention police never wondering why a drunk guy might get kicked out of a bar. But noo that would be smart, but we have drama to push and so our scooby gang with power of friendship have to save their friend.
P.S Im gonna mention one part which seems to be overlooked, but trying to have a romantic relationship and then having sex with woman who your recently deceased friend wanted to marry is fucked up on so many levels that trying to paint horny pants in any positive light after it is fucking impossible.
5.Animation is good but out of place, as rest of show is just silly mess, such realistic and dready art style only solidifies what it wanted to be and what it actually turned out to be, a failure. Although fight scenes especially boxing matches were fluid and filled with momentum.
6.Sound tracks are lacking, while opening is good as it sets up mood for tough prison life its out of place for second half show which is alot more light hearted and happy per say. Ending song was rather good, not something worth listening on its but nether the less well done. Its hard to say anything about rest of the sound tracks. none of melodies exactly sticked or made impression on me, likely because what ever scene they accompanied was uninteresting.
This isn't a a mature show, its a children's show with vastly unfitting art and illustration. It has depth if you are a cyclopes. It has drama rivaled by cringiness of soap opera. It is nothing more that just a hollow, low effort shlock.
