I usually just rate an anime and not post a review but this one time it just feels necessary. I have seen a lot of garbage anime - but rarely have I seen such a garbage story. Scripted and in advance decided football matches that are so unbearable to watch you might as well skip every single one of them as you have to sit through match after match where the team that was being told to lose will just stand on the field watch the opponent score goals, do nothing and at best just feel down about it.
It does not help that you have to watch the main character being the only one (later on one of the few) on the team that wants and tries to win regardless, instead his own teammates actively give their best to lose, hinder him to win them the match and constantly talk down to him. - Yes, they are just silly children and yes, this is an anime but again, it doesn't make any of this more bearable or easier to watch.
A "holy emperor" (a child) deciding which of the two teams wins and loses, even decides the exact score the match needs to end with made all the scripted matches completely pointless to watch or get excited about.
There is a lot of character development happening yes, but in no way does any of that make these matches any more bearable to watch. And in no way would I ever want to recommend Go to anyone. Watch the previous season/arc (Inazuma Eleven), that one is amazing. If you still want to give it a try, I highly suggest to skip at least the first dozen episodes.
