I haven't watched the original Japanese version, but I guess I could say this one is already a great film to watch.

Characters:
Each of the characters' stories is relatable especially of Zhang wei's. The passion, motivations and aspirations in life is well presented. . The development is also well-rounded.

Plot:
I don't know much about sport movie plots, but i guess this one has enough twist and the turn of events seems okay.
Well balanced comical and serious parts.

Acting/Casts:
Despite seeing new ones here, they have portrayed it very well i guess.

Music:
I definitely love the soundtracks as well as the sfx seems fitting.

Rewatch Value:
Will totally rewatch this.

Overall:
If you need some dose of motivation, you'll definitely get some from this film.

I'll edit this when I rewatched it
