Well that was just my opinion. I agree, the movie trailer looked interesting.
I followed McCrystal's career a bit and read his book A Team of Teams, none of it suggested anything but a very bright, high achieving guy. So seeing him portrayed like an insensate klutz in the movie made me think this is just more Rolling Stone style straight up garbage BS.
Rolling Stone has always seemed mostly like junk to me, but after they published that outrageous story last year of a campus rape at University of Virginia last year, which at first seemed so appalling but then seemed a bit hard to believe after just thinking about it some, and sure enough turned out to be total fabrication and was retracted, I fully realize they are a completely worthless, massively biased entity.
