It reminded me of Great Teacher Onizuka (which I'm not a fan of), especially the beginning when we have two bullies which we make feel terrified to let them know how it is to be a victim. Magically, that instant, they turn into great guys with great personalities. Wow...
My main 2 problems with this drama is that it deals with problems too easy and too artificial and that the show is too wordy. The main hero is reciting a pretty poor script time after time, but it changes everything. The father is abusing his own child. Let a boring teacher give him a boring speech with strong voice. There. Problem solved. Ofcourse, we have friends helping each other and caring for each other (or learning to care), but the focus is still on talking teacher who simply get bolshy, nothing more.
The absolutely WORST thing we see in episode 2, when a coach is willingly destroying his stundent's knee (by damaging training), just for... chances for a date with her rival? It's not only sick as it is, but having an evidence of his wrong-doing, everybody's ok with him staying as a coach for a team and not taking the slightest punishment. I can't believe how horrible idea is this...
There are good parts of the show - the casting (for the most part) were pretty good (especially the students with Kenta on the lead), but the main hero is just a meld of motivation talk and staginess. Overall, I always had the feeling that the guy is not teaching anything, but just mesmerazing with talking and looking cool (or posing to be that way).
