Catherine's Craziness

To decide whether Catherine is crazy or not one would have to determine their definition of crazy. Does Catherine seem crazy because everyone expects her to follow in her father’s footsteps? Is Catherine crazy because all math magicians are crazy? In my opinion Catherine is just paranoid that she is crazy which in turn makes her seem crazy. When the audience finds out that it is actually Catherine’s proof and not her father’s, I think that is the way the director is trying to say “Catherine is not crazy”. The way Catherine’s sister treats her like a child also doesn’t help Catherine’s well being. Because Catherine is being treated like she is crazy she is going to question herself on whether she is crazy or not. Throughout the movie the audience is supposed to have the question “is Catherine crazy?” in their heads. Up until the point of finding out it was Catherine’s proof I do think she is crazy, but once seeing the proof is really hers I think she is normal and just paranoid. The way Catherine is always confused in the movie portrays her as crazy. Once the director revealed it was her proof the confusing look she has throughout the movie comes to a stop, she appears more stable at the end and looks normal.
