In a word of cardboard characters and poor writing, The Dead Zone is a joy to watch. I have enjoyed every episode and some episodes have been excellent.
The only tragedy with this series is not with the series itself but with the way USA handles the scheduling and marketing. Most of the time I don't know when the season is going to begin or when the new episodes will air. Scheduling is erratic and promotion is often non existent. Someone in the USA main office must not want this show to succeed. Frankly, it's an amazing testament to the show's appeal that it still is in production despite this utter mismanagement.
USA, please recognize the gem you have in both Monk and The Dead Zone and, at the very least, air them on a regular schedule on which we can rely.
