It is quiet, restrained, unfussy, and has, at its heart, an injustice so grave it will make your blood boil. You will also cry.

Despite its weighty themes, Stephen Frears' film is almost as much a comedy as a drama.

The movie is a bit of a puzzle coming from atheist co-writer Steve Coogan and the script grapples with these big questions of religion, class, and justice in a way that's far beyond the typical teary human-interest story.

There's tightly packed power packed in 'Philomena' but I'm not entirely convinced that Frears knows where to aim his punches.
