Shakespearean
I thought this film had echoes of Shakespeare in it. In plot and character, although not in dialogue, anyway. Hennessy reminded me somewhat of a Lear-like figure: this once-terrifying warrior king of the IRA now struggling to hold together a political legacy. His wife got a bit Lady Macbethish a couple of times. The politics, the sexual liaisons, the vengeance, all of it was played at such a high-stakes level - I don't think we see enough of that.
I was worried, going into this, that it would be a rather obtuse action movie, cool and slick without depth. But what I found was an excellent political thriller with a lot of interweaving plot angles.
