Mark Wahlberg does a perfect job of portraying a detached veteran who has no respect for the government, and really brings the character to you. He is backed up by an outstanding Michael Pena and Danny Glover who add to the film like no one else could. The only real complaint is that Kate Mara's character, the widowed wife of Swagger's best friend seems to only play two emotions, distressed, or hysterical, and it does get annoying, though she plays the part well. Elias Kosteas did a good job playing Jack Payne, a borderline psychotic government agent, though at times his part seems over the top.
All in all this film blew me away and I couldn't have loved it more. Anyone who is into action movies of any kind definitely needs to see this movie.
