Query: worth watching once

I did enjoy the slow burn of this film, the understated, almost leisurely approach to tension.But I checked out emotionally for the same reason that I check out emotionally from most films: when the behavior of the characters on the screen resembles in no way human behavior as I recognize it. In the case of this film, that happened when the guy was kissing the girl in the elevator, while the assassin was standing right there.Yeah, right.
