In “Dangal, ” is Mahavir a domineering stage father, using his kids to live out his failed dreams? No doubt. That’s why he prays to have sons. But when God blesses him with daughters, he transfers his obsession with molding a champion right onto them; as a coach, he’s both a domineering egotist and a de facto feminist. If the movie has a theme, it’s that Mahavir is a patriarchal thinker forced, by circumstance, to move into the 21st century. He’s a lot like India itself.
