I know most people wish they'd try "icon" films, and there's been some discussion about why that probably wouldn't work as well as you might initially imagine (i.e. many of them are more well-executed tropes than dimensional characters capable of carrying a feature, though good writing could change that). I agree that some of the originals provide great premises and foundations for original films, though, particularly the ones that are different enough from their obvious inspirations.
The Forsaken or even Dead Man's Pier probably skew too closely to The Fog, for example. But material like Dead Exposure, Scarecrow, or Wicked Growth feel like they have their own identities with fertile ground.
