One thing I learned as a film major is that there's a subset of film critics who will believe every good movie (especially one with any theme of "creation") is a metaphor for moviemaking. Infertile couple? It's about the director's struggles with the movie studio. Mad scientist genetically engineers a monster? That's clearly how the director feels about his creations once they're in the public eye. These critics are right sometimes, but I think there's a large element of "When the only tool you have is a hammer…" at work as well.
