I have watched MI-5. The british programs are so rich and complex. One in particular I really enjoy is "cracker" Americans tired to make a version of cracker but it was cancelled almost immediately. The american cracker was good looking and thin.....now we all know cracker is a chain smoking, fat, gambling, drinking shrink?? My all time favorite series tho was Morse...I could kill colin dexter for the way he ended morse's life...
