Moria says, "The Legend of Hell House was the single best work that [director] John Hough ever turned out. 1000 Misspent Hours calls it "one of the last great English horror flicks". DVD Talk says, " It gets moving right from the get-go, tells the story without any excess padding or draggy moments, and does manage to pull off a few surprises with what happens to, and around, the characters." Twitch Film closes by saying the film is "still nerve-jangling, especially if you're watching alone, late at night, and wondering what those strange noises are, emanating from the shadows behind you." Horror News has praise:
The Legend Of Hell House’s direction and cinematography are impressive, the compositions are suitably atmospheric, utilising split-focus and high, low and wide angles, and finally, the film’s electronic score (by Delia Derbyshire and Brian Hodgson of the Electrophon company) is one of the creepiest ever committed to film.Horror Express calls it "an atmospheric and impressive entry in the haunted house genre." Rotten Tomatoes has a critics score of 46%.
