'Unthinkable (2010)' is, essentially, a morality play, a bleak exploration of the effectiveness and - more importantly - ethics of torture. Its themes are rather interesting and it stirs up a lot of interesting questions. How do you weigh one life against another? How far will you go to protect the innocent? If you have to cross the very line that defines you - as an organisation, a nation, a human being - to do it, where does that leave you? Are you better than that which you fight? There are no easy answers. It's all very intriguing and, in effect, rather grim. The ending (extended from its initial finishing point) signifies the flick's brutal overall outlook. It's an engaging experience but it takes a while to get going and is, on occasion, a tad 'schlocky'. It's never quite as compelling as its premise, despite its solid performances and generally good writing.

Still, it's a solid affair that should get you thinking. That's not something that can be said about a lot of similar stuff.
