The true horror inspired by this film will be what you'll want to do to yourself after you wasted your time watching it. You'll want to claw your eyes out, scoop out your brains with a rusty trowel, and pierce your ear drums with roofing nails.
This movie isn't just bad, it's stupefyingly bad. The acting is atrocious, and the direction is even worse. Barry Corbin has a small, uncredited role in this film, and after having watched it, I am convinced that he had a clause in his contract stating that his name would not overtly be linked to or associated with this putrid waste of celluloid. If I could have given this movie anything less than one star, I would have.
To be honest, the main reason that I watched the movie was because Catherine Mary Stewart was in it. I loved her in "Night of the Comet", and "Weekend at Bernie's". After having seen her in those films, I was hugely disappointed by her performance in "Ghoul". She took cloying and maudlin to new depths.
None of the children in this movie could act in even the most remote definition of the word. Take an episode of R.L. Stine's "Goosebumps"... ANY episode.. and it would seem like the remake of "Evil Dead" or "The Conjuring" compared to "Ghoul".
I haven't yet read the novel that inspired this movie, but I am given to understand that it is a decent read. I don't know how closely the movie adaptation paralleled the book, but some of the elements of the movie were beyond any semblance of believability, particularly the closing scene between the "ghoul" and one of the child protagonists of the movie.
The story behind the "ghoul" is that the evil, drunken, abusive father of one of the three children central to the plot was the foreman over a mining crew. One of the men under his supervision asks for the day off of work because his wife doesn't feel well. Greedy for a promised bonus if some assignment is finished early, the foreman declines the miner's request, which leads to tragic consequences. The miner goes home after work, and discovers that his wife killed their twin sons, and then herself. Apparently, driven mad by his grief, the miner becomes a recluse and goes to inhabit the now abandoned mine and tunnels.
The evil, drunken, abusive father/former foreman is so wracked by guilt for what he has done to the miner's family that he helps the miner trap his victims. Here we have another clichéd horror movie plot... kill the males, kidnap the females. Gee, never seen that before.
In another review, Brielyn Sexeny is mentioned. Yes, she is attractive, but her big scene in the movie is when she goes berserk and gets into a mixed martial arts brawl with the clothes on her backyard clothesline.
By the way, Brielyn Sexeny's character kills more people in the movie than the ghoul does.
If you haven't seen this movie... DON'T. It really is that bad.
