i can not believe i watch this whole movie . another ishtar in that i keep wait for it to get good and which never happen . the sound be terrible and go from too low to hear the conversation and to blare sound in second . the plot be absolutely implausible and the acting be mediocre and although keaton do his usual good job a a mental case and although be typecast in that role could certainly be consider a negative . the director know absolutely nothing about hospital and medication and science or anything of a technical nature . sociopath . i wonder how they come up with that diagnosis . there be so many error and goof and thing wrong with this movie that if one be to list them all it would possibly set some kind of record . demerol a a general anestetic . a motorcyclist on the freeway wear a non dot or snell off road helmet . san francisco . paper wall move when tapped and helmet just appear out of thin air and gun point one direction but hit thing in another and light appear and disappears and there be barely a scene in the move that doesn not contain some kind of error . my wife and who be an rn in an oncology unit finally leave the room before the end of the movie so upset over all the medical error . i give it a 2 only because of keaton acting and else it certainly would have get a 1 .
