I have spent intense 2 hours watching this stuff. I know how everyone hates it when there's too much humane in a blockbuster, but the whole character building is one of the trademarks of a good Russian movie. I grew up watching Russian military movies thanks to my father and to tell you honestly this whole movie just breaks my camaraderie meter. The plot could have been more original, but let's be honest the fighting scenes are god damn awesome, the characters are well written, the choice of casting (I knew each one of these actors from TV films or series or movies since I was a small girl) is simply tremendous. I felt like throwing things and crying over the whole Lyuba/Spam send scene, only Russian movies can make you feel completely attached to a character even if the character is a tremendous a-hole. The whole Resident Evil reference if anything is maybe over-exploited, but I wouldn't have it any other way. So, this movie is awesome, but I don't suggest it if you are not the kind of person who likes to know the background of characters and military thematic.
