#14 Romeo and Juliet , tragedy and tragic flaw

one criticism of the play is that it is not a true tragedy in which the main character (s) is ultimately brought down by his tragic flaw ( a character trait such as ambition, indecisiveness, greed) which they really can't help...it is who they are) if it is a tragedy - and it says it is in the title - then what are Romeo and Juliet's tragic flaws?
