Watching "The Fourth Horseman"/"The Time is Now" can be a draining experience. It's 90 minutes of television that are so bleak and grim that it's hard to believe they made the air. Though the acting and story are strong, the episodes are still tough to sit through.
The deaths from the virus are perhaps the most horrifying images "Millennium" ever depicted, perhaps because they are in such everyday scenes...the farmer's morning chores, a Mother's Day dinner. These nightmarish scenes, coupled with the collapse of Frank and Peter's friendship and Lara's descent into madness completely turn the series on its head. Lance Henriksen and Terry O'Quinn knock these shows out of the park. Their intensity bubbles over into full-blown confrontation, and it's great to see the result. O'Quinn especially is good as a man torn by his faith and the reality of evidence against what he has invested so heavily in.
And of course, the final moments...easily some of the darkest and most depressing on TV. Had "Millennium" ended here, it might have ranked among the most memorable series finales of all time.
