it was good to see that they took parts of the manga and were faithful despite all the unedited history of Riota.
This is what I liked the most as well. It's probably because Inoue-sensei himself directed the movie. I've read an article that he was against animating the interhigh part before because the animation studio planned to change it.
I only found the image of Akagi very ridiculous
It wasn't Akagi at all... haha
They looked more handsome, but the animation style made it difficult to show the usual expressions the characters had in the original anime. :)
