This is a threadbare, lamentable movie that barely has enough professional sheen to pass as a commercial feature. There's clearly an idea behind it and some hard work and effort went into it, but not enough to make any investors stump up the cash needed to make it come to life. Camera work, editing, sound and special effects all look like home movie work. The sound is particularly bad, it's very muffled and distorted, and (as other reviewers have pointed out), the colour of the movie has suffered badly on most available copies, and everything looks a shade of muddy orange. Thank goodness for colour hue adjustment on modern PCs, which at least helped me improve this on my viewing!
The plot sees a family move into a large new home. The daughter, a young girl named Cathy, finds a creepy doll and becomes possessed by the spirit of it's former owner. Under this influence she terrorises and kills friends and family members in some rather odd supernatural ways. Most of what happens in the running time is brain-testingly boring, but a few scenes did actually stand out for me. The one strength of the film is the young Randi Allen in the role of Cathy, who has just the right kind of ominous stare to make her character actually appear creepy, and she even has some acting skill. All the other acting is dreadful. Cathy's mother Vivian is particularly intolerable, plus she has the weirdest zombie eyes of any actress I've ever seen without makeup.
A low budget can work if the film is saved by a good script or good acting, but here we don't have the required acting talent, and putting that together with a dreadful script and poorly planned scenes really make the film fall apart from beginning to end. It's actually a chore to watch. The only times I l did find I was enjoying looking at the screen was when Randi Allen was cursing and screaming at people, and a couple of times when the eyes on a spooky portrait in the attic went all evil and glowing. This spooky portrait, plus the doll with it's eyes sewn shut are the only two decent ideas in the film. Actually, I'll be generous, although I moaned about the terrible ambient sound, some of the creepiness of the film does come from the soundtrack, when some effective slowed-down voices and laughter adds atmosphere in some of the spooky scenes
The makers of Cathy's Curse have a lot to be grateful for in Randi Allen for playing the title role of Cathy straight. If this pivotal role had been bungled by a really bad child actress, then "Cathy's Curse" would be a total laughing stock worthy of Doris Wishman comparison. Actually, that might have propelled it into higher cult status. As it stands, its just one more super-cheap attempt at serious horror that fails to deliver.
