I didn't watch the first season and never read the manga, but I did enjoy this show. There were some completely over the top stupid moments, but for the most part it was okay. The genuine messages the FL (teacher of Class 3-D) were well delivered. It's a story of not giving up, even if the world judges you without knowing who you really are, it's about true friendship and even family. I don't think it's meant to be realistic at all, but to give a warm feeling.

The "students" actors all did well with their acting; anger, laughter, tears, regret, etc. The FX (makeup from the fights) sucked. The OST wasn't great, but the episode music was okay. Some fight scene choreography wasn't great production wise; so obvious.

The other teachers were ridiculous and same with the parents. I would've given it a better score, then just 6.5/10 overall, if the students (at least the 5 main guys) had at least once came to the aid of their teacher or even helped her with a love interest. There needed to be a little more depth between the teacher and those 5, to make her influence more impactful. They could've done that and taken out some of the "comedy" bits of the supporting characters from the teacher's "family."

Over all the handsome guys and a strong FL, made up for the short comings.
