One doesn’t need press notes to sense that Roshan Sethi’s “A Nice Indian Boy” is personal for its creator too. A lot of films at SXSW this year felt like political statements, but Sethi’s film feels more like a call of kindness in this world. It is a remarkably sweet film, the kind of nice comedy that feels increasingly hard to make well in a landscape when so many films come with cynical agendas. It is sometimes disappointingly sitcom-ish in its structure and visuals, but the amount of love that Sethi and writer Eric Randall (working from a play by Madhuri Shkar) have for these characters is obvious and contagious. You’ll grow to love them too.
