During the time this drama is set, I was deployed to Landstuhl Regional Medical Center as a member of the USAF medical corps. While a number of the depicted situations weren't perfectly accurate, they did portray the essence of combat medicine and captured many of the emotional dynamics as well.
I liked very much how the many conditions and dynamics of deployment were at least broached: insurgents, local terps, illicit recreational sex, lesbian (bisexual?)soldiers, military politics, reaching out to locals and some of the inherent trust issues that exist on both sides, and the heartbreaking violence requisite of life during wartime.
Not all kudos here, for the writing and character development could have been better, and had the tendency to lapse into stereotypical characterizations, i.e., arrogant surgeon (Dr. Hill), idealistic internist (Dr. Trang), over-achiever female surgeon (Dr. Gordon), and no-nonsense commander (Dr. Marks). Also a number of plot twists disappointed for their already-done expectedness in other media.
I appreciated this show and its complex elements; of course the medicine wasn't perfect nor were the uniforms/military protocol, but all in all, it was a rather insightful look into military medicine at its finest--saving lives under the incredible pressures of war. Additionally, I do make the note which must be bared in mind: Hollywood (or Toronto), rarely depicts occupations and their intricacies accurately simply for lack of dramatic effect. It is the provenance of the creative arts to take license with 'the truth.'
All said, I enjoyed this show and was able to comfortably relive some events from my own life, which was an engaging experience. For a fairly comprehensive look into combat hospital life, check out the 2008 documentary by Terry Sanders, "Fighting For Life" filmed at stateside and in-theater military hospitals.
Finally, in reading the varied reviews here, I find the disinterest/criticism of certain comments to be less about the content of the show and more reflective a commentary on the American (and Canadian)public's apathy toward these wars and its less than one percent of Americans engaged in them. I hope some entity will find the wherewithal to reincarnate this show and bring this much-needed perspective back on air in the future.
