I am a movie lover
It takes a lot for me to say that I disliked any movie. But this... my god.
The story could have been told in a 3 minute short. There are minimalist films for the sake of story telling and then there are minimalist films for the sake of being minimalist films. This was the latter. Showing me a nice rack for 2 minutes is not going to change my mind, though an appreciated try. I can't understand why Clooney did this.
I recommend you stay away from this. If you want to see a far better, similar assassin/spy movie with much more content and emotion then I recommend In Bruges. If you want to see a far better, similar minimalist/mercenary movie with much more story and lasting effect then I recommend The Hunter. (Both are currently on Netflix I believe)
