Shaolin Soccer's ending hits so hard
You feel the brothers pain, all those years wasted learning Kung Fu only for it to be deemed useless in society and becoming trash collectors, dishwashers etc. When Sing recruits them, they realize there's no other way out but with each other.
They succeed, and Kung Fu is restored to its glory in a new form, in daily life, sports, and for us, in cinema.
It's partly why I could never rank KFH above SS, I'm too sentimental about this.
