Even though I'm not a fan of the Marine corps, this movie was amazing. The war Choreography was spectacular. You could the bullets hit the Aliens and every explosion kill a Marine. This film reminded of Black Hawk Down, it also had a mix of Independence day to it. I like the reference to World War 1 Devil Dogs with the phrase Retreat Hell. I still think that Black Hawk Down was a better film because it happened for real but this movie kicks serious butt.
