Query: Well-Acted but Hampered by Poor Special Effects

The Crawling Eye (1958), directed by Quentin Lawrence and starring Forrest Tucker, is a film about alien creatures residing in the Swiss Alps with the ability to disguise themselves in radioactive vapor. The action is slow-going throughout much of the film, which centers around a human female discovered to have a telepathic link with the aliens, as well as a series of murders in which the victims are decapitated. Later, however, in one of the film's more interesting subplots, the aliens decide to possess the bodies of their victims rather than decapitate them, for the purpose of killing the aforementioned female (they don't want her exposing them with her telepathic ability). The big eye creatures themselves, with their long tentacles, look ok, but film plummets in rating from good to fair because of below average special effects. Adapted from a British tv series The Trollenberg Terror.
