This movie could've turned very cliché very fast considering it being an American spy thriller about Russian spies, but somehow it managed to stay grounded. It's an unemotional, unapologetic thriller which takes its characters and lets them have realistic behavior throughout this movie, making the ending even more believable and satisfying.

This movie also takes its time to develop its characters and its story. So do not watch it if you're only into fast paced action rides. The action is subtle but given its premise completely sufficient.

However, I would've loved a little more complexity in its main story line, given this movie being about spies. But, seeing the already more than the average length of this movie, you wouldn't be able to keep the audiences in their seats.

All in all one of the better movies of the year.
