While this film is marketed as a horror movie, it doesn't really start to get creepy until the very end when a lot of the secrets alluded to throughout are finally revealed. The construction of the story was quite well done, which started in the past with Farley in a mental institution being interviewed by a doctor. He tells the story of what led up to his present situation - with occasional interruptions for outbursts and changing tapes - which not only gives a clear and concise story, but also leaves room for Farley's commentary as well.
Warning! Spoilers Ahead!
Farley's resentment of his father had continued to build, especially when his father insisted that he never see his friend Scarlett again. The two of them had planned to meet up at the Wilder family cabin, which was located in a part of woods that was supposedly haunted; a place that Farley's father had forbidden him to go. But Farley went anyway, and was confronted by his father. Farley finally snapped and stabbed his father with a pumpkin-carving knife. The murder is witnessed by Katie, the next-door neighbor whom he despises, and while chasing after her, he runs into several more individuals who also feel the wrath of his blade.
Oddly enough, the real terror of these woods is not Farley, but a group of strange creatures called Trogs, who live there and are responsible for many disappearances and deaths, including Farley's mother. In the midst of his murderous rage, he heard screams and found that Scarlett had become their latest victim. Enraged, he killed the beasts with his bare hands, then resumed his rampage.
The interview format was a great one to use (being vaguely reminiscent of Anne Rice's Interview with a Vampire), but it was only utilized for the first part of the film. The rest of the film had the the doctor lobbying the mayor for Farley's temporary release to help rid the town of the Trogs, since Farley was the only one who had confronted them and lived to tell about it. This finally lead to a semi-happy - if not eerily appropriate - ending. But it was oddly paced as opposed to what had previously been a very smooth story.
In addition there were a couple things that seemed odd or surprising, such as Farley's habit of tubing down the river, even in the fall which, in New England, can get very cold. Also, when Farley is on his rampage, his knife never gets bloody, nor does his clothing. And, when Scarlett is dying, while the the gouges in her neck looked good, they didn't seem sufficient to kill her, especially not so that she would die so suddenly.
