I love field hockey. First team sport I ever played and my big sister was on a team in high school before that. So I'd be a sucker for this film no matter what. But on top of being about field hockey, it's about a women's national team, and it's about sexism, and has a lot of cultural insights into India.
And the title song is catchy.
Chak De! India (Let's Go, India!)
Because it's so much about the game and has lots of game footage from India's various world cup games with other countries, it's not about suddenly breaking into dances and songs that have nothing to do with the plot. Oh well, can't have everything.
