Too many miniseries these days are long, lazy, stagnant streams of consciousness, nothing more than something to hang commercials on. A good mini should be like a thick book that you want to—but can't—read in one sitting, filled with characters you get to know better than most of your relatives, plot lines that rope you in and don't let you go, lush photography and writing good enough to quote over coffee. A mini should be more than a movie. This week, hallelujah, we have two such maxi minis: NBC's Fatal Vision and the syndicated A Woman of Substance. Enjoy.
