This is an art movie, which reminded me of movies from the American movie maker David Lynch. His last movies tend to be psychological thrillers, and at the end, you donâ€™t understand what has happened, and have to watch the movie again. I actually like such kind of concepts.
No Smoking is also a psychological thriller/drama about smoking and cigarettes. Therefore, I would warn those who donâ€™t like such kind of movies or dramas in general.
