I'm trying to think of a better-made action thriller, but I can't think of one. What is immediately striking about this movie is the stunning cinematography - every shot feels meticulously thought out. But it then becomes apparent that in terms of execution, this movie pretty much has it all: acting from everyone involved simply could not be better, the sound work is fantastically atmospheric and somehow always finds the perfect music, and the editing is as good as it gets - creative and mood-setting.
On the other hand, the story is fairly standard save for the intriguing premise, and pacing falters slightly near the middle. I found myself thinking, in the final minutes of the film, that my opinion of the movie would all depend on how it ends. The fact that I had a stupidly huge grin on my face when it did cemented my opinion that this is pretty much my favourite action thriller as far as execution goes.
