Jack Ketchum is the maestro of extreme horror fiction, and thus far all of his film adaptations have been surprisingly superlative! Honestly, I could've never imagained novels such as "The Girl Next Door" and "The Lost" could be made so beautifully, respecting the source material while never shying from the extreme violence, either. However, I'm a bit wary; both "Off Season" and "Off Spring" are truly amazing (the former being my favorite horror novel of all time), but at the moment Ketchum is 3 for 3 on the film market. Let's hope the films are of the same quality level as their predecessors...
