In "Four Dreams," the two-parter that opens the season, Bridgette dreams what her mother dreams--except the child's visions take the form of cartoons; meanwhile, "Mother's Little Helper" finds Ariel and Allison seeing the same visions from very different points of view. Joe, too, is increasingly fleshed out. The role of the spouse who struggles to understand but can't really get what his partner is going through is a tough one, but Joe's harrowing experience as a hostage is an important sub-plot throughout the final seven episodes, the last three of which (a triple-header, if you will, as all three involve a serial killer whose grisly m.o. earns him the nickname "the Recapitator") feature Neve Campbell and Jason Priestley in recurring roles. Of course, this is hardly a typical police procedural; the Law & Orders and CSIs of the world cover that ground. Any TV show helmed by Moonlighting creator Caron will have its share of eccentric touches. Thus we get episodes like "The One Behind the Wheel" (Allison is possessed by a mouthy, repugnant crime victim, but Joe insists she pretend to be herself so as not to freak out the kids) or "Better Off Dead," an amusing and touching tale of a ghost struggling to accept his fate. Overall, though it has its weaknesses, Medium remains one of TV's most eminently watchable series. Bonus material includes deleted scenes, a few featurettes, and occasional commentary tracks. --Sam Graham
