The show has it's up and downs. The first thing that draws your attention is the time travel aspect, depending on the viewer you may or may not like this theme as for me I'm interested in it because depending on how they incorporate it they can make an interesting story.
The time travelling idea is interesting because it is used constantly to bounce back between the present and the past in order to change the outcome of events while I liked this, unfortunately the way it is done involves using two people; the main character goes into the past while the other person in the present helps trigger it. This is what constantly kept me from enjoying the theme because when the past was changed the MC would return to the present BUT the other person who helps trigger the time leap still maintained their memories of everything which didn't make sense. While I understood that you could put it down to him being unaffected and tied to the MC but logically it just didn't make sense how the person in the present had their timeline changed but they still were able to recall events that should have happened but never did. This felt like a huge error that constantly stood out.
Moving on to the characters, I wasn't fond of the whole idea of gangs being idolised because it felt so stupid and there was a lack of authority that kept them in check, so they were constantly doing anything as if it was some fantasy world where only children were roaming free. You instantly notice this when it reaches the point where 12 year olds are on motorcycles roaming about. As this story involved gangs/delinquents the dialogue and interactions were very cliche, so everyone you come across really feels similiar.
The pacing of the story felt good for about the first half of the show and then after somewhat of a big turnaround of events where a major milestone was reached, it felt like after that point the story sort of forgot about it's purpose it started to slow down as well as dip. You have this knowledge in your head but the story seems to be putting it to a side while you are thinking that huge event should be now pushing the story forward with it's momentum.
Another aspect that I struggled with is constantly wondering where to place this sort of story, if you ignore the time travel aspect, the story should be somewhat of a modern more realistic representation but there were aspects that took it in another direction where it felt like it was fantasy; the lack of more adult interventions, 12 years olds who are monstrously strong as well as not really looking or fitting their age, people getting hit across the head with metal bars and it not phasing them. So many of these small random unbelievable situations keep happening that make it hard to place, it's trying to fit in too many genres which makes it jarring, either be fantasy and have every be superhumans or not, don't include a bunch of them in a setting where everyone else appears to just be a regular person, it stands out far too much.
While the show isn't terrible, it's also not amazing. It's balanced out by the story which can be interesting against all the small details that stand out that you somewhat have to ignore to enjoy and see what comes next.
