Monstrous has a great 50s soundtrack and setting. It also has Christina Ricci on top form. What the movie doesn't have is anything new or interesting to say, the plot has been done ad nauseum and the 'twist' can be seen from a mile away. It's such a shame as Christina Ricci is a great actress and really should be given more interesting work, she isn't on the big screen as often as she deserves to be.
