For the life of me, I don't understand why this film has a 4.9 rating on IMDB. This is a really good movie that relies heavily on the notion that it's what you don't see on screen that is far more terrifying that what you actually see. In this regard it succeeds admirably. Most gripes seem to be that the movie deviates too much from the book. All I can say is that I never read the book so get over yourselves. A movie is a movie. A book is a book. They are two different things so try to enjoy it for what it is rather than what it is not.
Watcher stars 80's teen heartthrob Corey Haim as Travis, a likable teenager who takes in a super-intelligent stray dog only to find it's being pursued by a far more sinister creature form the same genetic research lab. Watchers is based on the Dean Koontz novel of the same name. Director John Hess does a great job of keeping the action moving along and keeping the tension pretty high. While he has a rather small list of directing credits I think he does a great job with this film and brings out good performances from all of his actors.
Speaking of which, my favorite character is Lem who is played by the always creepy and intense Michael Ironside [Scanners, Highlander 2]. He is wonderful in every film I've ever seen him in. You are always in good hands when he appears on screen and he does not disappoint in Watchers. Kudos also to Sandy the Dog who plays Furface. She is a fantastic animal companion in this movie and is definitely one of the stars of this show.
Here's some bonus trivia. The executive producer for Watchers is noneother than Roger Corman and this is one film he can be proud of. Jason Priestly  also makes cameo as "boy on bike." Watch closely or you'll miss him!
Finally, Joel Goldsmith, the son of legendary composer Jerry Goldsmith, gives us a nice score that is avoids many of the 80's cliches so prevalent in movies of that era. His work on Watchers sounds like something his father would have composed. I consider that to be a high complement, indeed.
RATING: Very Good.
