Unknown was always going to draw comparisons with Taken, and in my opinion, unfairly; because although they share the same lead actor, the similarities end there.
In fact, the two films couldn't be more different.
Taken was an OK film in my opinion. I'd give it three stars. I found it pretty flat to be honest. The story line was boring and the action, although there was plenty of it, couldn't have been more run of the mill.
Taken is the exact polar opposite of Unknown.
Where Taken's story line was boring and simplistic, Unknown's was riveting. It was slow to build where as taken was in your face; and 'slowly' draws you in and keeps you guessing. I found myself very engaged in it.
And whereas Taken's action was non stop but mediocre, I found Unknown's to be sparse (at first) and very exciting when things boiled over.
I'm surprised by some of the harsh reviews for this film - but then reading some of them, I see that people either didn't watch the film to the end or are fans of Taken. Well, I'm sorry, but you can't comment on a plot until you know the twist and see the big picture, and if all you want is action, action, action and can't enjoy anything else you're a bit of a moron.
Unknown is an excellent espionage thriller, and I thought it worked very well. You might guess one of the twists by about a third of the way through, but you'll never see the whole 'big picture' right until the end. And isn't that just how films are meant to be...
