I've been collecting VHS tapes for years and haven't come across 'Night Frights'. Low-budget 90s horror can be a goldmine for unlisted gems. Try asking in some VHS collector groups; someone might know more!
I just make sure my tapes ain't near any windows where sunlight can hit 'em. Fades the covers and can mess with the tape. Dust covers are cool too if you're really looking to keep them pristine.
I know the series ur talking about. Had a kinda eerie feel to 'em, didn't it? Wouldn't surprise me if they ended up in some private collection. Stuff like that doesn't just vanish. Someone's got 'em, for sure.
