Once again, you and I think very similarly. The anti-soldier bias has bugged me this entire season because it is SO out of left field. I know the Doctor's personality changes a little bit with each regeneration, but that's usually been things like specific quirks, not his core beliefs. For him to have picked up a brand new prejudice out of nowhere is kind of new, and raises some rather disturbing questions about regeneration which I don't think Moffat intended to raise.

And I gasped aloud when I realized that was the Brigardier. I'll forgive almost every other sin this episode committed for that moment when the Doctor saluted him.
