King Kong

 Although laughable by today's standards of visual effect, King Kong is undeniably impressive for 1933. This trailer for contained too much screaming, and not enough diolouge and clear narrative. Also I think that putting text over a scene that reads "Look at these scenes, right out of the picture!" is both distracting and irrelevent. To understand that this trailer was released the same year as Frankinstein I'd say as impressive as the effects are, the editting as design of the trailer is majorly flawed, making it a worse trailer.
