This is really high class movie and I really love it. I do not watch many movies under the Action category, but this was great and now I am bigger fan of movies of this kind. If a movie can keep me focused for the full movie time, that's really great. It is really hard not to smile while watching While We're Young. What determines the phenomenon of this movie? It's realism, taking care of psychological probability?. It's a movie for everyone, I'm sure you'll like it after watching.
