The actual story is excellent, cast brilliant, political insight fantastic.
Let down by some of the drama. Albania is pro U.S.A. I doubt the airport guards pointed guns at the American staff.
An F.B.I. agent arriving in U.K. with a firearm?
A red phone box, black cab taxi and Manchester United football shirt doesn't mean it's Manchester. Scotland Yard ( inspectors/ Chief Superintendent, his rank changed ) wouldn't travel to Manchester without the local Police being involved.
There were only two people on the boat that attacked USS cole in Aden. ( The child was just added).
The bombing of the U.S. Embassy in Nairobi. The F.B.I. managed to get on a C130, fly from NewYork to Nairobi and the local emergency services were still arriving at the scene.
Fantastic, riveting series spoiled by silly drama/cheap/inaccurate bits that were not needed.
