Sidney Rosenzweig argues that such readings are reductive and that the most important aspect of the film is its ambiguity, above all in the central character of Rick; he cites the different names which each character gives Rick (Richard, Ricky, Mr. Rick, Herr Rick and boss) as evidence of the different meanings which he has for each person.
Sidney Rosenzweig tvrdi kako su takve interpretacije neznatne, te da je najvažniji aspekt filma dvoznačnost, iznad svega u središnjem liku Ricka; navodi različita imena koja svaki lik daje Ricku (Richard, Ricky, G. Rick, Herr Blaine itd.) kao dokaz različitih značenja koje ima za svaku osobu.
