Boring outside of a few standout scenes.
It was hard to be drawn into the suspense when the storyline was so obvious. Emily Blunt (and the audience) are left in the dark for most of the movie, just getting pulled from sketchy meeting to sketchy mission to sketchy meeting again until the big reveal at the end that *gasp* (spoiler I guess)
The government is working with the cartel and the CIA murders people! Who could've guessed.
