As a documentary, Too Big to Fail was excellent, with credible performances, a taut script and the expected HBO varnish. As a drama, its flaw was that for all the alpha male hubris on display, there was no redemptive suffering.

Without taking an partisan position on what happened... Too Big To Fail simply and clearly explicates a chilling moment in recent history. And for that, it has value.

Takes a topic that could have felt like homework and turns it into effective entertainment - even if that entertainment might teach you something along the way.

For a film shot in dimly lit offices inhabited by unattractively driven men in suits barking financial twaddle at one other, it was surprisingly involving.
