There are horror titles that are universally considered part of the canon of the genre, pun fully intended. The Whale films, Chaney and Lugosi and Karloff, the Hammer films, Val Lewton's work, and many more. It's a lengthy canon, running from the early nightmarish fever-dream imagery of "The Cabinet Of Dr. Caligari" to the freaky body-fearing obsessions of David Cronenberg, and every era is represented on the list in some way. The '80s had their high points, and I'd immediately name films like "An American Werewolf In London" and "The Thing" and "The Fly" and "Evil Dead 2" as classics from the decade.
I know plenty of horror fans who would call the original "Fright Night" one of those movies, and while I think it's solid and accomplished in places, I don't think it's one of the greats. It has personality. It has its charms. It is just fine. It has some clever ideas, and that goes a long way, especially in explaining the urge to add it to the lengthy lists of remakes no one was asking for.
