Major is such an underrated anime, and I absolutely loved watching it. The further seasons will almost definitely get higher marks from me. The main charm of the series in my opinion is the genuine nature of the drama and the interactions in the character. There was never a point when it came to the characters that I thought "This would only happen in anime". That's actually a lie, there is exactly one part where this did creep to mind and holds it back a little bit. Hoshino and Goro's dad got together way to fast to the point where it wasn't exactly believable to be honest. They literally got engaged before they even kissed (at least on screen).
The rest of the show wasn't exactly amazing, but well done. For the most part the sports scenes weren't too dragged out and somewhat believable, although I found the last game to be a little weak and dragged out.
Overall, very good show whose highlights is realistic drama, but it is held back a bit by minor details and sound & animation. It definitely did well as a base for future seasons to build on.
