William Goldman says that the last 15 minutes are the most important of any movie and that's what saves what is otherwise a sometimes fascinating but often dull film in "Pacific Heights."
The plot line is fairly interesting but feels rather drawn out through most of the film, until the fantastic ending pulls out all the stops and turns the film into something good. The writing in general is a bit contrived and the dialogue fairly wooden, but it isn't quite enough to destroy the film even early.
The acting is very uneven, led by a terrible Melanie Griffith and a middling performance by Matthew Modine in terms of screen time, but certainly controlled by the fantastic performance of Michael Keaton, one of the world's greatest actors. Keaton is especially fantastic in the final sequence, from his charming act with the old woman to his harrowing, venemous final scene there is a complete change in who he is and it is all the more frightening and powerful for the juxtaposition.
Schlesinger's direction, besides Keaton's performance, is probably the saving grace of the film. He manages to inject a beautiful dark style to the film that the script rather lacks but seems to want while also keeping us in a blunt reality with the plain, simple outdoor shots. His use of lighting and well-chosen camera angles wonderfully play up the situation.
Overall, "Pacific Heights" is a middling film with a fantastic performance by Michael Keaton and good direction by John Schlesinger that turns into something better with its fantastic, surprising, venemously satisfying ending. If you watch it, though, don't give up on it 'til it's over.
