You probably have watched the movie (I'll be talking about some important things that happen in the movie plus the summary line kind of gives away one of the main plots of the movie) and hopefully were as impressed as me.
Of course Bunuel has another plot going on, involving our main character (the doctor) and this guy who is pushed over the edge by his employer. The great thing about it is that everything stays within the main theme of the movie. Which of course is, that everyone is too much involved with themselves or their job to realize what is going on around them. See wife who's being cheated on, the doctor who's more into his new flame, than realizing the potential killer in one of his patients (husband). Maybe the only character who's ahead of most of them is the comic relief (from the police). But even he doesn't do anything to stop. So the end is inevitable. A commentary that also works today, the movie is timeless.
