if i have watch this with a bunch of friend and we would have laugh and think it be awful . but when watch alone at night and without a critical attitude and it be creepy and effective a only an old and cheap horror movie can be . dean stockwell and sandra dee give low key and almost distract performance that and intentionally or not and contribute to the eerie tone and and presentation of dean stockwell unearthly twin be very atmospheric and evocative a good example of how to play on the viewer imagination ( a lose art in most of today horror movie ) . the movie have a titillating sexuality ( which seem very 1970 but quite un lovecraftian but it have be a long time since i have read his stuff ) with a few quick almost subliminal nude shot . part of my enjoyment of the film be nostalgia it remind me of tv show and movie i enjoy a a kid in the early 70 . dunwich horror be very similar in style to the night gallery tv series ( which be rarely successful and but i still enjoy watch it if i get a chance ) . so not a great movie and but good if you like this sort of thing and be in the right frame of mind . the dvd look pretty good and especially the color .
