Quite predictable, pretty unrealistic and still very enjoyable. That being said, this movie is everything you can expect it to be. Quick and interesting action and even if you can predict what's gonna happen next (sometimes precisely to a second) you still will enjoy seeing how they made it happen. As for acting: Rebecca Ferguson's lovely, Simon Pegg'g good, Ving Rhames Jeremy Renner and Simon McBurney are adequate for their characters, and Tom Cruise... well he's the way he is, if you love him you'll love him here and if he annoys you... ;) All in all it's an action movie and if that's what you expect than you surely won't be disappointed.
