It's pretty damn cool. I actually prefer it to Taken because the plot is more complex. It's a political, psychological thriller that doesn't disappoint. I've purchased three copies - a digital copy for myself from iTunes and two combo-packs, one for my dad and one for my step-dad, both as Father's Day gifts. I highly recommend it.
And my favorite part is that it's one of the few movies in the world with twists that are absolutely impossible to predict. You may have a hunch for a couple smaller twists, but there's a new twist around every corner.
