While in retrospect I actually liked a fair amount of this movie, its glacial pace and lack of… well, stuff happening, prohibits me from giving it a general recommendation.
An American film with European sensibilities.
Its pace works to advantage of the whole thing.
Stuff does happen; its just more subtle than typical spy thriller. Can see why it doesn’t have wide mass appeal. But it’s a thinking persons work of art – thoroughly enjoyable.
Definite classic and great in balance with say ‘RED’ which covers similar territory in entirely different ways.
Should I Go See It? 
YES.

Recommend both.
