That it is the perfect tragedy is the critical opinion on "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).
Specifically, nothing is irrelevant in the play. All characters and events link to form a net in which Theban King is caught and from which he cannot escape. In fact, Oedipus thinks that he comes up with successful avoidance and escapist strategies that in fact just make more realizable his fate as the killer of his own father, the husband of his own mother and the half-sibling of his own children.
