Yesterday, I saw the last of the three "Rings" movies. Ho-hum. CGI is great. So is a good book. CGI of a good book is, however, just eye-candy. "Cyborg" is a movie that, lacking money and computer graphics, was forced to tell a story. Michael Rennie (you know him as "Klaatu") is a man/machine from the future, come back to correct a few mistakes. His "high" tech looks a bit like your grand-dad's ham radio did about the same time this movie was made, but so what? Garth (Rennie) isn't here to show us ray guns or cell phones. (Who knows? Maybe his gizmos are all camouflaged to resemble '60s-era devices.) What he is here for is to undo the damage of some bad decisions (many of which will remind you of "The Terminator's" SkyNet, but you decide yourself if there's a connection).

Alas for Garth, if he succeeds, it may have dire consequences for him personally. That fact gives him a poignant nobility that many films, then and now, could use, but lack. Time-travel stories often rely on that kind of wrinkle for their drama, and I think that's an inherent weakness of the time-travel sub-genre: they all tend to ask the same question. Still, this one asks it well and Rennie's skillful performance leaves you exquisitely uncertain of just what the Right Thing to Do would be, in such a situation as his character finds himself.

Yeah, "Rings" was great. But so was this, and they don't make 'em like this one anymore.
