It's like an onion. Many layers working correctly together. The title may sound like a bad late night teen movie but quickly showed its many layers it to be much more a social commentary than a war movie. Excellent cast overall and the leads were particularly stellar. Based on real events and people, within a short real life time-frame of 1967 America and the Tet offensive, lies this very good film. Partially a heavy dose of beers and bros from Philly juxtaposed with 1960's America's unflinching coursework on a culture of war escalation like we did in 1945, says Bill Murray as The Colonel. Those sentiments juxtaposed with the Prophetic words from Viet Nam War Correspondent, Russell Crowe, "It isn't the truth that hurts us. It's the lying that hurts...". Well worth your time!
