With eleven episodes (plus a "bonus episode" from December, 2005) spread out over three discs, The Dead Zone is at its best when dealing with the series' one ongoing storyline: i.e., the machinations of Congressman Greg Stillson (Sean Patrick Flanery), the dumb, arrogant puppet of sinister forces who aim to put him in the White House, where, by accident or design, he may preside over Armageddon, according to Smith's visions. Unfortunately, only three Season Four episodes address that story, and they fail to advance it much further; indeed, Episode 11, "Saved," serves mainly as a cliffhanger for subsequent seasons. The remaining stories, in which Johnny helps the cops pursue various psychopaths, perverts, missing persons (including a Lennon-esque rock star presumed dead many years before), and such, are good but considerably more pedestrian. Still, while other shows may have cooler special effects, more action, and larger doses of tension-relieving humor, The Dead Zone stands out for its overall smarts and classy production values. Bonus features include deleted scenes, audio commentary on a few episodes, and a featurette focusing on production design. --Sam Graham
