This is an excellent movie, but don't watch it expecting it to be purely a dark comedy. There is a lot of humor in it--often very bizarre humor--but it is primarily a very powerful statement about what can happen when, for the sake of social acceptability, a human mind is forced into a mold that doesn't fit. In my opinion, the British ruling class was chosen to illustrate this point only because they do have very rigid rules about what kind of behavior is socially acceptable and what is simply "not done." It's statement about the dangers of excessive self-repression apply equally to us all.
