Loach's film isn't technically a musical, but it has that same spirit, that same let's-put-on-a-show vitality. Even its politics come from that world: In its juxtaposition of stodgy, slightly daft conservatism with communal glee and celebration, this isn't a nuanced, sober work. It's a film that stacks the deck ideologically, but does so with such energy and freewheeling charm that you roll with it.
