Being a ghost story horror film this movie is so high quality it is insane. There is no bad acting or stupid decisions of the main leads. Quite the opposite. The actors Michelle Pfeiffer and Harrison Ford act their asses off. The directing of Zemeckis is so good it is hard to explain. This movie has a lot of impossible shots in it. It is showy, but that is kind of the point. For example, the camera might be looking at people from beneath objects, through stuff that should be solid. In one shot the camera clips through the floor and looks at the actors from under the floor. While they have a wooden floor. This was a hard visual effects shot with CGI floor. I mean Zemeckis went insane.
Francis Ford Coppola, a director behind things like The Godfather and Apocalypse Now did not direct Vampire's Kiss. It was directed by Robert Bierman. A director who did mostly work for TV. And who's directing style is not necessarily bad. I don't think he is bad. The movies do not feel terribly directed. It's just it seems that as a director he is not necessarily exciting.
