Murphy's house was probably in a crummy school district. That has a way of really lowering the price of homes.
RoboCop 2 was pretty distasteful and Irvin Kershner should have known better. How a director who helmed some really beautiful films as well as the best damned Star Wars movie got stuck on this thing is a minor mystery. And Leonard Rosenmann's usual stiff "it worked for Combat!" score doesn't help. The "RoboCOP!" chorus theme was laughable. The best thing RoboCop 3 did was bring back Basil Poledouris.
You seen any of those videos where people edit the Poledouris score back into some Robocop 2 scenes? It fits quite well.
