This movie is almost perfect. My only problem is that the score and music is not the best, and the World Cup scenes with the cheering and commentating was cringe as hell most of the time. Too over the top. The cast was great, especially the two lead. The other members in the team had a good backstory too. This was a feelgood, heartwarming movie and funny too. Also, even though it would've been nice to see a happy ending for everyone, I liked it that not everyone had it. My other problem is that we didn't get any confirmation about In Sun's girlfriend, or maybe I just missed it. That Japanese girl was her because we never saw her again.
