As basic entertainment, this is kind of fun. It's a nicely plotted film if you don't think too much. The plot involves a doctor who has psychotic tendencies and acts on them fairly frequently. Because he doesn't get caught, he feels vindicated. He applies this logic to other murderers as well. He is played pretty well by John Forsyth. He has a relationship with Barbara Bain from the Impossible Missions Force, and hopes to marry her. I'm surprised his last name isn't Bluebeard, because he seems to have a thing for trophies. The acting is credible in the made for TV venue. It's nicely done. As a previous writer said, it's a little like those Link/Levinson productions, ala Columbo. It moves along nicely and there are lots of surprises.
Now for the other part. There are so many coincidences and potential pitfalls that it would be really hard to make the plot work. Anything could mess it up. There's also the fact that the person murdered first knows about Forsyth's history and still allows him to perform surgery. He also baits him about his past. There had to be other avenues he could have taken, knowing what he knows. There's also a frame up that really would have to be so obvious to anyone with a shred of investigative insight.
The characterization is good. I really liked the nurse, Rita Shaw, who has a handle on everything. She is Forsyth's main adversary, and he doesn't even know it. She has always played those kinds of characters and, like people in her profession, she's the guts of the operation.
I would recommend this film if you aren't too picky. It will keep you involved.
