Perhaps some 'lowbrow' novels can become classics if they're written well enough.
For instance, I'm not sure if Salem's Lot and Let The Right One In are lowbrow or highbrow, but in my opinion they're better than Dracula, even though that book is regarded as a classic which pretty much started the vampire genre.
Salem's Lot brings vampires into modern times, and LTROI is an excellent take on child vampires. Having child vampires is nothing new but I don't think it's ever been done as well as it is in LTROI.
