Cannibal Troll is not the best of horror films, that's definitely certain. The acting is average, but admittedly better than the usual Scott Chambers's ultra low budget horror flick. The troll isn't actually a cannibal as it neither eats human flesh or troll flesh.
The plot was terrible and involves several friends going on a sort of hen-do type trip before the main character gets married (cue unusual and out of place lesbian side plot!) her husband to be is apparently not thought of too well by the girls who outright call him boring within the first ten minutes to the weak defense of the main character. The actual troll's mask is quite silly, but again, I've seen worse. There are a couple of somewhat effective tense moments, but they're quickly destroyed when we actually come face to face with the troll in the second half. There's a ridiculous sub plot involving a Priest and, what I think, was a holy handgun.
3/10: Cinematography and acting are average, but it's brought down in every other department. At least it wasn't as boring as some other ultra low budget films.
