Re: Zero Dark, it was sombre but I think the audio in the beginning is emotional manipulation. Everything following that opening audio can be justified by the suffering of those victims and questioning anything is equated basically with questioning the suffering of those victims. I don't know if it was intended but it works very well I think. In addition, it seemed to me to glorify and humanize the SEALS as basically a bunch of nice guys doing a rough work.
Anyway, I guess it's a matter of interpretation. I just found Argo better, or at least less offending.
