Horribly written. The 1970s original version of this movie, which starred Robert Culp, was immeasurably better. I wish I could obtain that one, but apparently it's unobtainable. In the original, Culp's character was a mousy marshmallow guy with no temper at all--until the end of the movie when he finally blew up, went ballistic, and got his justifiable revenge.
This movie, however, completely is a complete lost cause as soon the ignorant screenplay writer has Rob Lowe manifest an angry temper--which he continues to manifest all throughout the movie. Lowe's character only makes matters worse for himself, so that the audience really cannot sympathize with him, leaving the viewer with no real reason to keep watching this lousy movie, especially since the supporting acting was rather poor all around. Or you might just find yourself so exasperated that you fast forward through most of this frustratingly bad movie, as my wife and I did.
You could seriously take a lot of guys right off the street, hand them a paper and a pencil, give them the gist of this movie and tell them to write a screenplay for it, and they would do a better job than this screenplay writer.
P.S. Jennifer Grey should have kept her original nose, which was very distinctive. The post-nose job Grey doesn't look bad at all, but she does look ordinary. And ordinary's not good when you're looking for acting work in Hollyweird. Now we know why we haven't seen much of Jennifer Grey for quite a number of years now.
